“…From the point of view of metal science, electromechanical processing can be attributed to a special type of surface thermomechanical processing. A distinction is made between high-temperature thermomechanical processing, where deformation occurs at a temperature above the recrystallization threshold, and low-temperature thermomechanical processing, where deformation occurs at a temperature below the recrystallization threshold [15][16][17].…”

The article presents the results of research on technology development and substantiation of the modes of strengthening the working surfaces of earth-moving machines by the electromechanical method. The types of wear and the appearance of defects on the working surfaces of the part are analyzed, taking into account the operating conditions. Based on the conducted studies on the study of surface wear, the arithmetic mean values were determined using the example of a plowshare of a bulldozer blade. A technology for restoring a part with subsequent electromechanical hardening has been developed. The influence of processing modes on the surface hardness was studied, and using a multifactorial experiment, a regression equation was identified, and optimal hardening modes were substantiated.

After plasma spraying, high‐velocity‐oxy‐fuel (HVOF) spraying is fast emerging as the most versatile deposition technique for thermal sprayed protective coatings. In this context, the present work aims at the deposition of a class of inter‐metallic/cermet coatings of nickel chrome boron silicium (NiCrBSi) and nickel chrome boron silicium+titanium diboride (TiB2) on 304 stainless steel substrates using high‐velocity oxy‐fuel spraying route. The cermet powder is prepared as the feedstock by mechanical mixing of the powders prior to spraying. Different coating samples are obtained by varying the flame‐to‐substrate spray distance (40 mm, 80 mm, 120 mm, 160 mm and 200 mm). These coatings are characterized in terms of their adhesion strength, deposition efficiency, thickness, and micro‐hardness by conducting tests as per the ASTM standards. The surface and interface morphologies of the deposited coatings are studied using scanning electron microscopy. The possible phases present in the coatings, and the transformation of phases during deposition have been explored by x‐ray diffraction analysis. It is found that the coatings exhibit fairly good interfacial adhesion, micro‐hardness, and thickness values that varied significantly with the spray‐distance. Further, the premixing of titanium diboride in nickel chrome boron silicium improved the mechanical and microstructural/compositional properties of the coatings.

“…Thin-film coatings provide an inexpensive yet effective means of protecting a wide range of industrial components and processing tools. They have thus attracted significant research attention in recent decades [1][2][3][4][5][6]. Transition metal carbide coatings are of particular interest due to their many outstanding properties, such as hardness, high wear resistance, good thermal stability, and superior chemical stability.…”

CrC and NbC carbide coatings both have good mechanical properties, wear resistance, and corrosion resistance. The present study seeks to combine the two coating systems in order to further enhance their properties. NbCrCx and NbCrCxNy coatings (where x and y denote the atomic percentages of carbon and nitrogen, respectively) were deposited on SKH51 substrates using a radio-frequency unbalanced magnetron sputtering system. The mechanical, tribological, and corrosive properties of the coatings were investigated and compared. Among the NbCrCx coatings, the NbCrC61 coating showed high levels of hardness, excellent adhesion strength, and good wear resistance. Among the NbCrCxNy coatings, the NbCrC55N5 coating showed high adhesion strength and hardness and excellent tribological properties. However, for nitrogen contents greater than 16 at%, the adhesion strength was dramatically reduced, resulting in poor tribological performance. Among all of the coatings, the NbCrC49 coating showed the best corrosion resistance due to its enhanced crystallinity, high adhesion strength, moderate surface roughness, and high sp3 C-C bonding ratio.
