Abstract: Two kinds of wear-resistant alloy coatings with the microstructure of "ferrite+VC particles" (VCF) and "lath martensite+VC particles" (VCM) were prepared on the base metal of Q235 steel plate by using powder plasma surfacing equipment, and the microstructure, hardness, wear resistance and wear morphology of VCF and VCM coatings were observed, respectively. The results show that the microstructure of the VCF coating is a ferrite distributed with hard phase particles, and the microstructure of the VCM coating is a lath martensite distributed with hard phase particles. The hardness and wear resistance of the VCM coating are higher than that of the VCF coating, indicating that the wear resistance of the coatings not only depends on the number of hard phases, but also has a significant relationship with the microstructure type of the coalings matrix.
