The demand for materials capable of reliable service at elevated temperatures is steadily increasing. Therefore, this research presents the manufacturing process of MIG-CMT linear Inconel 625 cladding onto the 16Mo3 base material to create high efficiency and corrosion resistant bimetallic material. Microstructure of the bimetallic material was examined by SEM, which revealed NbC, TiC, and MoC carbides within the structure and dendrites that were directionally solidified and aligned parallel to the thermal gradient. Dislocation in microstructure was examined by TEM analysis. The grain size and orientation were examined by EBSD analysis, which found that the grain size in heat affected zone was on average about 10 µm. Furthermore, the chemical analysis unveiled that the chemical composition of Fe decreased from the average value of 3.5–1.2% after overlapping with the second Inconel 625 layer. Micro-CT analysis showed that the bimetallic material exhibited minimum internal defects due to the appropriate welding parameters. Microhardness testing revealed that the highest value of hardness was measured between welded layers 398 HV0.1. The base 16Mo3 material exhibited a average hardness of 210 HV0.1. It was concluded that bimetallic material consisted of Inconel 625 and 16Mo3 steel offers a robust solution for industrial environments requiring high strength, corrosion resistance, and thermal stability such as the incinerating kettle.
This study explores the development of low-friction, water-based coatings tailored for industrial applications in pharmaceutical glass packaging. The study focuses on scalable deposition strategies to obtain durable low-friction coatings suitable for industrial implementation. To balance mechanical performance and application efficiency, two different application approaches based on a two-component coating (aminosilane primer and lubricant) were investigated. In the first case, the coating is deposited in two steps, while in the second, a single deposition step is used. Characterization through contact-angle measurements and X-ray photoelectron spectroscopy confirmed successful deposition of the primer on the glass surface. Scratch resistance tests revealed an increase in the critical load for fracture initiation from 4.5 N for uncoated glass to 6.5 N for the best-performing coating, indicating improved resistance to surface damage. Friction performance was assessed via tribological tests, which demonstrated that the primer–lubricant coatings achieved the lowest coefficient of friction (approximately 0.2), compared with uncoated glass (stabilizing at approximately 0.3 after an initial value of 0.5) and lubricant-only coatings (approximately 0.4–0.5), confirming the beneficial role of the primer in the coating system. Representative profilometry measurements indicated sub-micrometric coating thicknesses, while UV–Vis measurements confirmed that the coatings preserved the high optical transparency of the glass substrate, with average visible transmittance values above 90%. Furthermore, the successful implementation of the coating using an automated spray system demonstrates its potential for scalable industrial production. These findings support the potential of environmentally sustainable water-based coatings for pharmaceutical glass packaging by combining improved mechanical performance with preserved optical transparency and compatibility with scalable spray deposition.
