Residual stress distribution and wear behavior in multi-pass laser cladded Fe-based coating reinforced by M3(C, B)

A novel high hardness Fe-based composite coating reinforced by M3(C, B) carboboride was prepared by laser cladding. The microstructure and solidification process of the coatings were characterized. The residual stress distribution of the coating was studied. The wear resistance of the coating was te...
