Abstract: Four groups of WB-reinforced Ni-based coatings were prepared on EH40 steel substrate by laser cladding technology. Microstructural and phase analysis of the coatings, as well as an evaluation of their hardness and wear performance were studied. Microstructural analysis revealed that the coating consisted of γ-Ni, Cr2Ni3, W2B5, and WO3 phases. Coating hardness demonstrated a non-linear relationship with WB content, increasing initially before decreasing at higher concentrations, achieving maximum hardness (746.67 HV0.2) at 30 wt.% WB addition. SEM images of the dry wear tracks showed that the Ni-based coating exhibited significant plastic deformation on both sides of the scratches, indicating adhesive wear as the primary wear mechanism. Compared with dry friction, the wear resistance of the coating is significantly improved in liquid medium. The wear mechanisms under wet friction are primarily abrasive wear and abrasive erosion.
