This study fabricated a single-layer W alloy coating on H13 steel using the pre-placed powder laser cladding method. The optimal process conditions were determined by comparing coating quality under different laser power parameters, and the coating was successfully prepared. The micro-region composition distribution and phase composition of the coating were analyzed by EDS and XRD, and its microstructural evolution was inferred. The wear resistance was evaluated through hardness tests and friction-wear experiments. The results show that the coating prepared at a laser power of 320 W and a scanning speed of 300 mm/min exhibited the best quality, with a small amount of ZrC particles effectively regulating solidification and inhibiting crack formation. Cr and Co were uniformly distributed, while Mo and Ni contents were low. The coating microstructure predominantly consists of irregular white W, gray Laves phase (Fe₂W), and black γ-Fe, with minor amounts of fine Co₃Fe₇ particles dispersed throughout. The hardness of the coating (1 100-1 300 HV) was significantly higher than that of the substrate (420 HV), and its wear rate was only 50% of the substrate′s. Analysis of the wear tracks revealed that the predominant wear mechanisms of the coating were abrasive wear and adhesive wear, while demonstrating that ZrC particles could effectively enhance the coating′s forming quality, hardness, and tribological performance.
