Under the effect of applied fatigue loads, high stress concentration appears at the coating/substrate interface where cracks tend to initiate. In order to monitor the interfacial crack initiation, a two-dimensional cohesive zone model is introduced to actuate the magnetomechanical model to describe the interfacial damage evolution process by measuring the residual magnetic field. The variation of residual magnetic field strength at the interfacial pre-crack tip with loading cycles under the tensile fatigue tests is analyzed. Then, the residual magnetic field strength threshold of interfacial crack initiation is determined. The physical mechanism underlying generation and variation of interfacial magnetization is also revealed from the perspective of magnetic domain movement. Furthermore, the low- and high-cycle fatigue three-point bending tests are conducted to verify the applicability of residual magnetic field measurement for interfacial crack initiation monitoring. It indicates that this measurement method can provide the guidance of crack initiation monitoring for magnetic nondestructive testing of coating/substrate interface.

Prediction of manufacturing equipment’s energy consumption plays an important role in selecting appropriate process parameters for energy saving. However, it is difficult to model the energy consumption of metal forming equipment during the drawing process characterized by variable process parameters and dynamic loads. In this paper, a model was developed to quantify the energy consumption of a typical hydraulic press during the drawing process under a range of operating conditions. The hydraulic press studied consists of two different circuits and two controllable parameters, i.e., punch velocity and blank holder force can be set for drawing processes performed. To start, the energy flow during the drawing process was analyzed by using the energy conversion mechanism and components’ specifications to understand the detailed energy characteristics of each circuit. Then, orthogonal experiments including these two parameters at three levels were designed and carried out to find significant parameters. Finally, the contribution of each parameter, which was obtained from the analysis of variance (ANOVA) of the experimental results, was used to simplify energy flow modeling efforts. Consequently, a model of the press was established and used to predict the energy consumption of the drawing processes with different parameters. Good agreement with the experimental results was observed. The model can be used to identify parameters for minimal energy consumption, while the approach could be adapted to develop an energy consumption model for different hydraulic equipment.

The research results in Chaps. 4– 6 indicate that the metal magnetic memory (MMM) signals are essentially induced by stress concentrations. The relevant physical mechanism of the (MMM) signal has been studied, and various theories and models have been proposed. Some have found that the Hp(y) signals are distributed randomly for different materials, especially in the elastic deformation stage, while others have found that the Hp(y) curves have regular linear changes with increasing stress and have different features during the elastic and plastic deformation stages.

Due to the inconformity of the failure mode or damage degree in the remanufacturing cores as shown in Chap. 12, the corresponding repair process parameters in remanufacturing may also be different. Therefore, the mechanical properties of remanufactured products are affected by the status of cores, which can lead to quality fluctuations after repair. It is necessary not only to evaluate the damage degree of the cores before remanufacturing, but also to evaluate the repair quality after remanufacturing. Only in this way can unqualified remanufactured products be prevented from reaching the market.

After the damaged remanufacturing cores are evaluated, the cladding coating prepared by advanced surface engineering techniques will be deposited on the damage zones of the cores if they have remanufacturing value. As a typical remanufacturing repair technique, plasma transferred arc welding (PTAW) is commonly employed to prepare a cladding coating on a metallic substrate, which exhibits special advantages including a low dilution rate, intensive energy density, and high deposition speed. The metal powders are melted immediately when they pass through the plasma beam between the positive and negative electrodes.

In 1975, Misra found a transient magnetic field during crack propagation under low carbon steel tensile experiments. This result showed that spontaneous magnetic flux leakage was formed when the ferromagnetic materials were subjected to stress. Based on this, the concept of metal magnetic memory (MMM) was first proposed by Russian scholar Doubov in 1994, and MMM was applied in the nondestructive testing (NDT) field.

When the magnet exceeds a certain temperature, its magnetism will be weakened due to the increase in temperature and the thermal movement of the atoms. The magnetic moment of the magnet atom tends to be arranged in a random state, which leads to a decrease in magnetization. Therefore, temperature is another important factor that can impact the magnetic field distribution of ferromagnetic materials apart from stress concentration.

At present, the abovementioned metal magnetic memory (MMM) studies in Parts 2 and 3 mainly focused on standard specimens rather than real remanufacturing components. This is because the inconsistency of the size, shape, material and other factors of the remanufacturing components may lead to the dispersion of MMM testing results. Therefore, the fatigue test specimens with middle notches have mostly been used in previous studies based on national or international standards. Xu et al. [1] conducted tensile fatigue tests on 45 steel central crack tensile (CCT) specimens, and the variations in the MMM signals during fatigue testing were studied. Qian et al. [2] used a three-point bending fatigue specimen with a U-shaped notch to analyze MMM signals. Ni et al. [3] established the relationship between MMM signals and damage degree for V-notch specimens during crack initiation.

For the remanufactured components whose heat residual stress meets the requirements, the service performance of the coatings also needs to be evaluated afterwards. The evaluation of remanufactured coatings is the key to guaranteeing subsequent safety and stability during the service process. We also take plasma transferred arc welding (PTAW) as an example because it has become a very important surface engineering technique and has been widely used in the remanufacturing field.

The metal magnetic memory (MMM) is considered a new nondestructive testing (NDT) method for detecting early damage of ferromagnetic materials or evaluating the repair quality of remanufactured products. However, the research to date on the MMM technique has mainly involved the characteristic extraction of magnetic signals or investigation of their variation trend. This series of studies cannot help us to clarify the generation mechanism of spontaneous magnetic flux leakage and enable the quantitative evaluation of early damage and repair quality based on MMM signals. Therefore, the application of the MMM technique in remanufacturing engineering is seriously restricted.

Although metal magnetic memory (MMM) evaluation of heat residual stress and service fatigue damage for remanufactured coatings has been investigated in Chaps. 9 and 10, respectively, MMM evaluation is still unable to meet the requirements of holistic quality evaluation for remanufactured components. Generally, remanufactured components are composed of three parts: the coating, substrate and bonding interface. The coating/interface/substrate can be seen as a kind of metastable multi-material system, and the interface is a weak area where the stress, crack or fracture may first initiate.

From previous studies, we find that whether the magnetomechanical effect is caused by typical loads, such as tension, compression and bending, or whether the friction magnetization is caused by single and reciprocating sliding friction, in essence, the spontaneous magnetic flux leakage phenomenon is affected by stress concentration.

Apart from tensile, compression and bending loads, friction can also induce stress. Friction and wear caused by rubbing and snagging are the main failure modes of mechanical parts. Approximately one-third to one-half of the world’s energy is consumed in various friction types, and approximately 80% of part damage is caused by various wear forms. Therefore, to determine the residual life and ensure the remanufacturability of cores, it is desirable to detect the position of the wear scar and monitor the wear state during frictional wear before remanufacturing.

A large number of components, such as engine crankshafts, high-speed bearings and gears, are usually subjected to complex loads in service. Naturally, stress can be induced in these components by the applied tensile, compressive and bending loads. In addition, the stress level increases with the increase in loads or fatigue cycles. When the stress exceeds a certain level, the crack will initiate and propagate at the stress concentration zone, which can affect the performance and safety of the components. Therefore, it is necessary to evaluate the stress level to determine the damage degree or residual life, which can help us determine whether the damaged components need to be remanufactured.

Recycling carbon fiber reinforced polymer (CFRP) waste is unavoidable for the sustainable manufacturing and cost reduction of CFRP products. Supercritical fluid technology is an emerging chemical method for recycling CFRP waste, but its energy intensity and environmental implication are limited understanding. In this paper, the energy intensity and environmental impact of supercritical fluid technology were quantitatively assessed in CFRP recycling process. Then, the life cycle assessment (LCA) method was used to analyse the life cycle environmental impact of CFRP in two scenarios, scenario (a) using conventional waste disposal method, while scenario (b) with CFRP waste recycling process. The results show that the energy consumption of CFRP waste recycling is 49.21 MJ/kg using the supercritical n-butanol method, which is far lower than that of virgin carbon fiber production (286 MJ/kg). Scenario (b) with CFRP waste recycling has a lower impact than scenario (a) at nine environmental impact categories, including a 26% reduction of global warming potential. Besides, the energy consumption of the supercritical n-butanol method is 31% lower than that of the steam thermolysis method (71.64 MJ/kg) in recycling 1 kg of CFRP waste, which validates that the supercritical n-butanol method is a potential strategy for recycling CFRP waste.

There is a large amount of carbon fiber reinforced polymer (CFRP) waste generated annually, mainly due to the difficulty in recycling CFRPs. This work presents a novel additive manufacturing-based recycling approach that can be used to reclaim CFRP waste and to re-manufacture the carbon fiber into 3D printed composite parts. A trial of this idea was set up, in which carbon fiber was first reclaimed from CFRP waste using supercritical fluid and then mixed with Poly-Ether-Ether-Ketone to produce composite filaments. The filaments were then fed into a printer of fused deposition modeling (i.e., a 3D printing process) and the recycled CFRP parts were fabricated. The engineering application-oriented tests demonstrate that the reclaimed carbon fiber can modify the performances of 3D printed part effectively in terms of mechanical strength, electrical conductivity, heat conduction and wear resistance. This work illustrates that the additive manufacturing-based recycling approach offers a possible strategy to recycle CFRP waste and fabricate high-performance engineering parts with complex geometries, which are economical and environmentally friendly.

Although overlay coatings deposited via plasma transferred arc welding (PTAW) can effectively prolong the service life and improve the performance of components, cracks and pores tend to occur in the high-hardness and wear-resistant coating during the deposition process. Further treatment is thus necessary to improve the coating quality. Herein, PTAW-deposited Ni-based overlay coating was remelted using plasma transferred arc (PTA) under different remelting currents (RCs). The microstructure and phase composition of the coatings were investigated via metallographic microscopy and x-ray diffraction. The hardness, surface quality, and wear resistance of the coatings were also tested. The results show that PTA remelting could effectively eliminate the defects and improve the coating properties when the RC was controlled within a given interval (100-120 A). The type and content of the hard phase in the remelted coating were increased to enhance the microhardness and wear resistance. However, remelting with excessive currents resulted in the agglomeration and growth of the hard phases, which negatively affected the coating hardness and wear resistance. The proper use of PTA remelting technology to treat PTAW-deposited overlay coating is an effective approach for eliminating the coating defects and enhancing the coating properties.
