摘要：
As a new surface processing technology,laser cladding offers incomparable advantages over other surface modification technologies. However, the performance of the heat-affected zone of the matrix deteriorates,leading to non-uniform microstructures and the generation of defects such as cracks and pores in the cladding layer. With the increasing demand for the enhanced surface performance of metal parts,it is important to improve the heat-affected zone in the matrix and the microstructure of the cladding layer. In this regard,this paper summarises the influence of heat treatment-assisted,electromagnetic-assisted,and ultrasonic-assisted methods on the microstructure and properties of laser cladding layers. Further,the influence of the various methods on the mechanism of microstructure transformation is summarised. The results provide suitable directions for the optimisation of and further improvement in the microstructure of laser cladding layers,and the paper concludes by noting the challenges and future perspectives in this regard. © 2023 Cailiao Daobaoshe/ Materials Review.
