This work reviews surface modification techniques for improving the wear and corrosion resistance of 42CrMo steel. The advantages and disadvantages of various methods, including thermal spraying, deposition, hardfacing, laser cladding, nitriding, and laser surface treatment, are discussed. The review elaborates on the materials commonly employed in laser cladding technology, including iron-based, cobalt-based, nickel-based, and high-entropy alloys and reinforced composite coatings. Furthermore, the mechanisms and methods of improving the wear and corrosion resistance of 42CrMo steel are summarized. Finally, this review presents research shortcomings and future opportunities of surface modification techniques. This review also provides a theoretical guide for the application of 42CrMo steel.

“…The morphology of the nanoparticles can also affect the tribological properties of HEAs. The FeCoCrNi HEA coating contained spherical and irregular shaped WC nanoparticles were fabricated by Peng et al [ 102 ] The microstructures of the HEAs with spherical and irregular shaped WC nanoparticles were significantly different. There were massive carbides in spherical‐WC HEA coating, which showed much more developed than irregular‐WC HEA coating, while fish‐bone carbides in irregular‐WC HEA coating were more continuous and developed than spherical‐WC HEA coating.…”

Wear is an important form of material loss and failure, and it is usually inevitable in almost all mechanical systems with moving parts. The durability and reliability of engineering components are closely related to their wear resistance. Developing advanced materials to alleviate energy and materials losses in moving mechanical systems still remains a great challenge nowadays. The emergence of novel high‐entropy alloys (HEAs) that compose of multiple principal elements holds great promise for the development of materials with extraordinary wear resistance, due to their high hardness, high wear resistance, and excellent corrosion resistance. Herein, the current research progress of the tribology of HEAs under different conditions is reviewed, including high temperature, dry condition, corrosion solution, and oil lubrication. Specifically, the effects of compositions, microstructures, lubricants, and protective oxide layers on the tribological performance of HEAs are summarized. Furthermore, the underlying mechanisms that are responsible for the excellent wear resistance of HEAs under different conditions are discussed. Finally, the current challenges and the future outlooks are emphasized and addressed systematically. In view of the excellent tribological performances and the diversity of compositional design, HEAs have great potential to be applied in a wide range of mechanical systems to minimize wear.

“…For example, corrosion-resistant HEA coatings can be applied in the ocean, high-pressure-resistant HEA coatings can be applied in oil and gas, high-temperature-resistant HEA coatings can be applied in aerospace and nuclear energy fields, etc., [10,11]. At present, the preparations used for HEA coatings include mechanical alloying [12,13], thermal spraying [14,15], cold spraying [16][17][18], laser cladding [19][20][21][22][23][24][25][26][27], magnetron sputtering [28][29][30], and plasma transferred arc (PTA) [31][32][33][34][35][36]. Among them, PTA has the characteristics of simple equipment, high production efficiency, concentrated energy, less environmental effects, and metallurgical bonding with the substrate, which are beneficial for forming high-quality coatings.…”

The low strength caused by the single FCC structure of the CrMnFeCoNi high entropy alloy (HEA) limits its application in the field of coating. Here, we prepared high-entropy alloy coatings of CrMnFeCoNi with different ZrC contents on Q235 steel by a plasma transferred arc process. The effects of ZrC on the microstructure and properties of the CrMnFeCoNi HEA coating were investigated by optical microscopy, scanning electron microscope, and X-ray diffraction and by employing a potensiostat/galvanostat. The results showed that ZrC mainly existed in the coatings as a second phase, having little influence on the main crystal structure and micromorphology of the CrMnFeCoNi HEA coating. The hardness of the CrMnFeCoNi HEA coating increased with the ZrC content. ZrC can effectively improve the corrosion resistance of the CrMnFeCoNi HEA coating. In a 1 mol/L NaCl solution with 4 wt% ZrC, the annual corrosion rate was only 5.997% of that of the HEA coating. Nevertheless, the improvement in the wear resistance of CrMnFeCoNi high-entropy alloy coatings was not apparent with the addition of ZrC. Consequently, the addition of ZrC to the FeCoCrNiMn high-entropy alloy coating holds promise for applications in corrosion resistance, particularly in oceanic environments.
