“…In addition, the incorporation of Cr atoms can decrease the melting point of the obtained solid solution powders, and thus affecting the temperature gradient and growth rate of the coatings during the solidification process. When the Cr additive is 5 at.%, the grain size is the smallest, which means the Fe–28Al–5Cr coating possesses great grain refinement strengthening effect [ 30 ]. Moreover, according to the XRD results ( Fig.…”

“…The addition of rare earth oxides can effectively refine the reinforcing material within the coating, thereby enhancing its microstructure, reinforcing the tissue boundaries, and reducing defects [112][113][114]. The research of Cui et al [115] supported this finding by preparing Co-based coatings containing CeO 2 on the surface of 42CrMo. This demonstrated that the addition of CeO 2 can significantly decrease the dilution rate of the coating, preventing the elements in Stellite-6 powder from diluting into the matrix.…”

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.

“…Figure 5 depicts the flow model of the molten pool cross-section and the formula for calculating the dilution rate in MAM. REEs can efficiently lower the dilution rate [43] and improve metallurgical bonding between the cladding layer and the substrate. He et al [25] discovered that CeO 2 lowers molten pool viscosity.…”

Rare earth elements (REEs) doping technology can effectively control the microstructure and improve the quality and performance of materials. This paper summarizes the research progress of REEs in metal additive manufacturing (MAM) in recent years and briefly introduces the effects of REEs on the molten pool fluidity, purified structure, and interfacial bonding between the molten cladding layer and substrate. It focuses on the mechanism of the role of REEs in the refinement and homogenization of microstructures, including grain growth, columnar to equiaxed transition (CET), and elemental segregation. The reasons for the influence of REEs on the homogenization of the structure and elemental segregation are analyzed. The effects of REE type, content, and dimension on hardness and wear resistance are investigated. Finally, tribological applications of REEs in biological and high-temperature environments are summarized, and the impact of REEs-modified alloys is summarized and prospected.
