Our nitrogen atomized H13 alloy steel powder has good hardenability, thermal strength, wear resistance and high impact toughness, thermal fatigue, widely used in the manufacture of hot work molds. Wear is one of the main failure modes of H13 steel hot-working die. Improving the surface wear resistance of H13 steel is an effective way to improve the life of die. In this paper, the process parameters and microstructure properties of cemented carbide coating prepared on H13 steel by vacuum powder sintering were studied. H13 steel matrix was prepared by laser additive manufacturing technology, and Ni/WC composite coating was coated by laser cladding. The hardness of the coating was 16% higher…
