Abstract：

As a high-strength alloy steel, 42CrMo steel is extensively used in the fields of machinery manufacturing, automotive engineering, petrochemicals, and aerospace et al. due to its remarkable mechanical properties. Nevertheless, in order to cope with the harsher service environments, it is imperative to further enhance its wear resistance and corrosion resistance. This paper comprehensively reviews the research progress of laser cladding technology applied to 42CrMo steel at home and abroad. It examines the recent progress and existing problems in aspects such as the cladding materials, optimization of process parameters, microstructure and microhardness, wear resistance and wear mechanisms, corrosion resistance and anticorrosion mechanism of the clad coatings. Moreover, it looks forward to the development trend of laser cladding technology for the surface modification of 42CrMo steel, aiming to provide a theoretical basis and technical reference for enhancing the comprehensive performance of 42CrMo steel.

Key words： 42CrMo steel laser cladding process parameters wear mechanism anticorrosionmechanism
