摘要: 使用粉末等离子堆焊设备在Q235钢板母材上制备了“铁素体+VC颗粒”(VCF)和“板条马氏体+VC颗粒”(VCM)两种组织形态的耐磨合金涂层,并分别对VCF和VCM涂层的显微组织、硬度、耐磨性和磨损形貌进行观察和测试。结果表明: VCF涂层的显微组织为硬质相颗粒分布于铁素体中,VCM涂层的显微组织为硬质相颗粒分布于板条状马氏体中,且VCM涂层的硬度和耐磨性均高于VCF涂层,表明涂层耐磨性的高低不单取决于硬质相的数量,还和涂层基体的组织类型有着较大关系。

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.
