The phytochemical analysis of the butanolic extract from the leaves of date palm of Saudi origin resulted in the isolation of three major constituents, oleanolic acid (1), vanillyl alcohol (2), and β-sitosterol-3-O-β-d-glucoside (3), which had not been isolated from this plant or previously reported. Together, compounds 1 and 2 account for 1.0% of the butanol extract, which represents 0.4% of the mass of the dried leaves. The isolation of other known compounds for this plant such as fatty acids, lutein, and sucrose was also achieved in this study. The characterization and identification of the isolated compounds were conducted on the basis of Fourier-transform infrared spectroscopy (FTIR), 1H and 13C nuclear magnetic resonance (NMR), liquid chromatography–mass spectrometry (LC–MS), and gas chromatography–mass spectrometry (GC–MS) analyses. The findings of the current study will definitely increase the knowledge about the contribution of the constituents of this plant to its well-known nutrition, corrosion inhibition, and antimicrobial properties.

The quest to replace toxic chemicals in the nearest future is revolutionizing the corrosion inhibitor research world by turning its attention to plant biomaterials. Herein, we report the corrosion inhibiting potential of butanolic extract of date palm leaves (BUT) on the corrosion of API 5L X60 carbon steel in 15 wt.% HCl solution. The mass loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), linear polarization (LPR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), and atomic force microscopy (AFM) techniques were employed in the investigation. We also report the effect of intensifier additives, namely formic acid (FA), potassium iodide (KI), and zinc nitrate (Zn(NO3)2) as well as temperature on the corrosion inhibiting performance of BUT. BUT exhibits inhibiting ability but the extent of inhibition is dependent on concentration, temperature, and intensifiers’ concentration. At 25 °C, 200 mg/L BUT and 700 mg/L BUT protected the carbon steel surface by 50% and 88%, respectively. The addition of 3 mM FA and 5 mM KI to 200 mg/L upgraded the extract performance to 97% and 95%, respectively. Zn(NO3)2 performs poorly as an intensifier for BUT under acidizing conditions. The adsorption of BUT + FA and BUT + KI is synergistic in nature whereas that of BUT + Zn(NO3)2 drifts towards antagonistic behavior according to the calculated synergism parameter. Increase in the system temperature resulted in a slight decline in the inhibition efficiency of BUT + FA and BUT + KI but with efficiency of above 85% achieved at 60 °C. The SEM and AFM results corroborate results from the electrochemical techniques.

We prepared a series of polyurethane (PU) coatings with defined contents using poly(tetramethylene oxide)glycol (PTMG) with two different molecular weights (i.e., Mn = 2000 and 650), as well as polydimethyl siloxane (PDMS) with a molecular weight of Mn 550. For every coating, maximum adhesive strength and excellent self-healing character (three times) were found using 6.775 mol% mixed with low-molecular-weight-based polyols (PU-11-3-3). Defined 1.0 wt% CeO2 was also used for the PU-11-3-3 coating (i.e., PU-11-3-3-CeO2) to obtain UV shielding properties. Both the in situ polymerization and blending processes were separately applied during the preparation of the PU-11-3-3-CeO2 coating dispersion. The in situ polymerization-based coating (i.e., PU-11-3-3-CeO2-P) showed similar self-healing properties. The PU-11-3-3-CeO2-P coating also showed excellent UV shielding in real outdoor exposure conditions.

Hybrid sol-gel materials provide a favorable alternative to the use of toxic phosphate and chromate conversion coating to protect metal substrates from corrosion attack. Herein, a systematic study was performed to investigate the effect of metal oxide additives i.e niobium(V) oxide), titanium(IV) ethoxide, and zirconium(IV) propoxide on the structural and corrosion protection properties of novel hybrid sol-gel coatings applied on a mild steel (MS) surface. Nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) analyses revealed the introduction of structural changes on the parent hybrid polymer upon loading it with the metal oxide additives. Moreover, the gel permeation chromatography (GPC) studies of the functionalized hybrid polymeric materials proved higher polymerization extent in these materials in comparison with the parent polymer. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization tests have shown that the metal oxide additives displayed; to various extents, an enhancement in the barrier properties of the base hybrid coating for a MS substrate in a 3.5 wt.% NaCl medium. Zirconium(IV) propoxide additive showed the highest corrosion resistance as compared to parent sol-gel coating or other metal oxide additives. Scanning electron microscope (SEM) analyses indicate an excellent homogeneous coverage of the functionalized coatings on the MS surface with no signs of defects, delamination, or micro cracks behaviors. The present study gains deeper insights into the interactions nature between the oxide additive and the host polymer matrix.

Surface cladding and coatings are commonly used to protect structures against corrosion in corrosive environments. In this paper, electrochemical properties of friction stir diffusion cladded ASTM A516-70 with corrosion-resistant aluminum alloy grade 5052 are studied. The effect of process parameters, tool rotational and traverse speeds on the corrosion behavior of produced cladded steels was comparatively assessed. Electrochemical analyses revealed that the cladded steel sample provided good corrosion protection performance in comparison with the un-cladded steel substrate following an immersion test of up to 21 days in 3.5% NaCl medium. Increasing the tool traverse speed was found to negatively affect the corrosion resistance. Optimum parameters for the selected cladding system were found to be a 500 rpm tool rotational speed, and a 50 mm/min tool traverse speed for protection against general corrosion. Meanwhile, higher traverse speed demonstrated stable passivation behavior and, therefore, lower propensity for pitting localized corrosion. Post characterization of the exposed area indicated that tool shoulder marks were favorable spots for the accumulation of corrosion products.

The effect of embedding various metal oxide additives on the structural, curing, morphological, adhesion, and corrosion protection properties of a novel hybrid sol-gel polymeric coating has been examined using various characterization techniques. The coating formulation embedded with yttrium(III) oxide exhibited optimum low surface roughness, good adhesion to metallic substrates with elevated thermal stability, and enhanced barrier properties for mild steel substrates in 3.5 wt.% NaCl medium compared to the parent coating. Scanning electrochemical microscopy analyses indicated a dense, crack-free, and homogeneous nature for the coating layer on the steel. The coating’s degradation was evaluated using the scanning electrochemical microscopic technique.

A hybrid organic–inorganic sol–gel coating was successfully prepared and subsequently functionalized individually with five different metal oxide additives. The effect of the incorporated oxides on the corrosion protection performance and scratch-resistance properties of the hybrid base coating on mild steel substrates was investigated using electrochemical techniques, namely electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) as well as mechanical testing. The steel-coated specimens were immersed in 3.5 wt.% NaCl corrosive medium for two weeks and the results reveal an excellent corrosion protection performance by all coating formulations with a significant high corrosion-resistance property for the sample loaded with molybdenum oxide. Scanning electron microscopy (SEM) images proved the absence of corrosion signs, defects, micro cracks, or delamination on the surface of the coated samples. Compared with the pure hybrid coating, all the metal oxide-embedded coatings (except for the sample loaded with yttrium(III) oxide) show comparable aqueous contact angle values as well as enhanced hardness and adherence properties. No noticeable dependence was observed for the surface roughness parameters as a function of the type of incorporated metal oxide within the sol–gel matrix. Overall, the results of this study demonstrate that metal oxides can be advantageous to the desired properties of hybrid sol–gel coatings applied to steel surfaces.

The severe damage of gas turbine is due to the failure of the blade, in which the occurrence of a serious pitting occurred on the blade surfaces was evidence of fatigue marks in the fracture surface. This paper deals with the effect of semi-elliptical crack propagation on the crack path using a basic approach in predicting crack paths, namely, incremental methods. The crack position was chosen at the node coordinate where we have the maximum principal stresses. In this node, we have created a semi-elliptical crack and we have compared the results with the Stress Intensity Factors and T-stress values. The local fracture criterion of the maximum average tangential stress in the vicinity of fracture process zone including two terms of the Williams series solution for the mixed mode I/II loading has been used for predicting the angle of surface crack growth. The volumetric method (VM) for the compression-sensitive materials is described by a linear combination of the effective stress and the effective stress intensity factor. The results of our finite element computations based on a two-parameter fracture mechanics formulation showed that the T-stress has significant effects on the crack path.

A hybrid additive manufacturing (AM) and friction stir processing (FSP) was used to heal a crack in 6 mm thick Al 6061-T6 aluminum alloy. AL-6061 is usually used in H2 high-pressure vessel fabrication as well as aerospace applications. In this work, Al-Si powder was utilized to fill the crack, then FSP was applied to consolidate and stir the powder with the base metal to fill and close the crack zone. Effect of FSP parameters including welding speed and tool rotation speed on the quality of repair was studied. Various mechanical tests, as well as characterization techniques such as hardness test, optical microscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS), were employed to study the newly developed hybrid process on the quality of the repair. The investigation revealed that low rotational speed of 800 rpm results in minimum variation in microhardness. Moreover, the impact of welding speed on microhardness is smaller as compared to rotational speed.

Metallic pipelines and gathering tanks play a vital role during oil and gas exploration, production, transmission, and processing. These facilities are usually attacked by corrosion. The use of corrosion inhibitors is one of the most economical and reliable approaches to control the corrosion of oil and gas metallic facilities. This paper looks at the progress made in the development of sour corrosion inhibitors from early 1900 to date. Scientific literatures were reviewed. The review identified four classes of organic corrosion inhibitors for sour environments, namely, amine-based, imidazoline-based, polymer-based, and Gemini-surfactant-based inhibitors. The strengths and weaknesses of these inhibitors were highlighted. The review revealed that the patronage of amine-based chemistries has declined, and the current technology is based on imidazoline and quaternary salt chemistries. The existing knowledge gap and the future research direction in the area of sour corrosion inhibitors development have been highlighted.

Puffiness formation can occur during process of pipelines component fabrication and transportation or during construction, operation, maintenance and their repair processes. The present paper addresses issues related to pipeline design and associated with the unintended actions due to external loads or ground movements. These may introduce longitudinal strains in the pipeline owing to combinations of curvatures and axial forces. Such scenarios can be tackled with Strain-Based Design approaches. Elaboration on checking the strain capacity of pipelines was achieved via the material testing in which a full-scale test was performed on a pressurized pipe under bending load. Numerical modeling procedures for predicting the structural behavior using certain assumptions are also described in this study. The result in local buckling hereafter referred to as puffiness. Such local damages are associated with large plastic deformations, substantial changes of the pipeline geometry and mechanical properties of its material.

Using cracked pipes design standards and finite element analysis, the limit load analysis for pipes containing surface cracks was determined. The study was performed on five pipes of different diameters with a constant crack length and depth. The crack geometry is a semi-elliptical surface crack. The cracked pipes are subjected to internal pressures which are obtained from formulas of cracked pipes design standards. Due to the ductile behavior of polyethylene pipes, the failure occurs when the critical stress reaches a value equal to the ultimate tensile strength multiplied by a constraint factor. In this work, the constraint factor was calculated and its evolution with the pipe diameter was analyzed. Three different definitions of a constraint factor based on global or local approaches were also compared, so that a new failure criterion can be obtained. The new failure criterion makes the prediction of the pipe residual life possible which, in turn, facilitates a systematic approach to maintenance and replacement of pipes.

A wide variety of carbon nanostructured materials have been effectively inspected as nanofillers to enhance the overall performance of the polymeric coatings; however, their practical applications are still limited by the high cost. Graphitic carbon nitride (GN) is considered as the best alternative due to its low cost and unique structural and mechanical features. Herein, we synthesized the GN-MoOx nanocomposite and utilized it as nanofillers to enhance the corrosion resistant behavior of epoxy coatings on AA2024 Al alloys in chloride medium. The rod-shaped MoOx nanoparticle with a diameter of 25 nm was obtained on the lamellar surface of GN in Scanning Electron Microscopic (SEM) and Transmission Electron Microscopic (TEM) images. The structural analyses results validate the monoclinic phase and formation of the GN/MoOx nanostructure. The Attenuated Total Reflectance-Infrared (ATR-IR) spectra of GN/MoOx illustrate distinctive poly-s-triazine peaks from 1200 to 1640 cm−1. The electrochemical corrosion results reveal that the nanocomposite reinforced epoxy coatings can deliver a higher corrosion resistant performance and the maximum corrosion protection can be attained via reinforcing the epoxy coatings with 3 wt% GN/MoOx. Based on the obtained outcomes of this present investigation, we envision that the GN/MoOx nanocomposite has a great potential in improving the surface protective behavior of epoxy coatings on AA2024 alloy against corrosion in chloride medium.

This work presents the suggestion of a model for the prediction of the reliability of type III gas storage vessel under pressure, considering the geometrical and mechanical uncertainties using the Monte Carlo method. Using the hoop stress for each ply, the Monte Carlo method was used to predict the distribution function of the mechanical response. The random design variables of the aluminum liner; which is overwrapped by a composite manufactured by filament winding. Nine random design variables with uncertainties were selected, namely: elastic constants of metallic and composite materials, ply angles, thickness, and finally the mechanical loading (pressure). To ensure the accuracy of the obtained results, we have performed 105 simulations. The obtained results showed that the elastic properties of the composite materials have no significant influence on the security of the composite vessels type III in relation to the manufacturing parameters: which are thickness, winding angle, and the loading pressure. The probability of failure increased significantly when all the random variables were considered simultaneously.

Hydrogen plays a decisive role in many future energy systems. For these reasons, many researchers have been performed to see the effect of hydrogen on network canalizations. This paper was study the possibility of hydrogen transportation using the natural gas pipeline. In this paper, the effect of hydrogen embrittlement (HE) on the mechanical properties of pipe steels was examined. It appeared that the yield stress and ultimate strength were few sensitive to HE. However, fracture toughness and elongation at failure exhibited a severe decrease. Failure pressure established by different codes involved a flow stress which is a combination of yield stress and flow stress. Pipe defect assessment involved fracture toughness and flow stress upon using Failure Assessment Diagram (FAD) or Crack Driving Force (CDF) methods. In this paper, the consequence of hydrogen embrittlement on the failure and critical pressures of a pipe with a semi-elliptical defect was examined. The influence of assessment method, relative defect depth and working pressure were examined through the comparison of respective safety factors.

Hybrid sol–gel materials have been found very promising anticorrosive coatings for metal substrates. In this article, the synthesis of novel hybrid organic‐inorganic sol–gel polymer; starting from tetraethyl orthosilicate, (3‐aminopropyl) trimethoxysilane, dimethoxy‐methyl‐octadecylsilane and polydimethylsiloxane, silanol terminated precursors, is reported. The hybrid polymer has been further loaded individually as well with five different metal oxides, then deposited on mild steel panels. All cured coating formulations have been characterized using thermogravimetric analysis, contact angle measurements, electrochemical impedance spectroscopy, vicker‐microhardness, surface roughness, and critical load analyses. Results have revealed that the parent coating exhibits excellent thermal stability and hydrophobic nature with minor observed changes on the two properties for the metal oxide‐loaded coatings. Electrochemical impedance and visual inspection results indicated excellent corrosion protection performance for all metal oxide composite coatings (except magnesium oxide) on steel when immersed in 3.5% NaCl solution for a prolonged time. Furthermore, the coating containing molybdenum oxide exhibited a maximum hardness, homogeneity, and adherence to the steel surface. The developed coating formulations in this study can be considered as a promising alternative to the currently‐used toxic chromate and phosphate coatings. © 2018 Wiley Periodicals, Inc. J. Appl.
