“…Various discontinuous plate-like oxide films emerged on the coatings' surface after heat treatment, underscoring the significant influence of binder structure on corrosion resistance. Liu et al [10,11] successfully prepared WC-12%Cr 3 C 2 -6%Ni coatings and WC-12%Co-6%Cr coatings on 42CrMo steel substrates with the surface engineering process of high-velocity oxygen fuel spraying and sealed them with sol-gel aluminum phosphate inorganic sealant. The findings revealed that the application of a sealing treatment could enhance the wear and corrosion resistance of the coatings.…”

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.

“…[13][14][15] Among them, the high melting point, low coefficient of thermal expansion, and high hardness of WC powder create favorable wear resistance. 16,17 Doping of the hard phase can effectively improve the properties of laser cladding layers; however, the direct doping of particles to enhance the cladding layer creates several problems, such as significant differences in thermal expansion coefficients between ceramic particles and the substrate powder, and an increasing trend of porosity and cracking due to irregular microstructure, aggregation of particles, and contaminated particle surfaces. 18 In contrast, in situ growth of the reinforced phase overcomes these problems because the reinforcement is uniformly distributed in the coating with good interfacial compatibility and sufficient bond strength between the reinforcement and the substrate, and various comprehensive properties of the molten cladding layer are achieved, such as microhardness and wear resistance.…”

Laser cladding technology can obtain a cladding layer with good metallurgical bonding with the substrate and excellent performance. In situ growth of hard phase can effectively solve the problem of uneven distribution of reinforcements directly doped with hard particles. In this paper, 45# steel was adopted as the matrix material, WO3, B4C, Al, and Ni60 powder were used to prepare laser cladding and in situ synthesized WC (Tungsten Carbide) hard phase reinforced Ni‐based cladding layers. The effects of different laser cladding parameters, powder particle size, hard phase content on the microstructures and electrochemical properties of in situ synthesized WC hard phase reinforced Ni‐based cladding layer were analyzed. The results revealed that when the (WO3 + B4C + Al) mixed powder content was 25%, the bulk particles of WC phase in the cladding layer were most uniformly distributed in the cladding layer, which enhances the mechanical properties of the cladding layer. When the B4C particle size was 5 μm, the microhardness of the cladding layer was significantly higher than other cladding layers, and the enhancement mechanism of hardness by B4C is due to the Orowan strengthening caused by too small particle size of B4C.
