摘　　要：以无缝钢管生产线上U形轴的基体材料表面等离子熔覆层为研究对像,采用等离子熔覆方法制备铁基/碳化铬+钼复合层,采用光学显微镜、扫描电镜和能谱分析金属基/陶瓷复合粉末对于等离子熔覆层的组织、结合界面及硬度性能的影响.结果表明:等离子熔覆层与基体之间具有良好的结合界面;随着碳化铬颗粒加入量的增多,组织中块状不规则组织增多,该块状组织为富铬组织,说明碳化铬的增加导致碳化铬聚集;随着碳化铬含量增加,熔覆层的硬度提高.可为高温金属间磨损工件的表面强化提供参考.The plasma cladding layer on the substrate of U-axis in seamless steel pipe production line was taken as the research object.Iron based/chromium carbide and molybdenum composite layer was prepared with plasma cladding.The effects of ceramic composite powders on the microstructure,bonding interface and hardness of plasma cladding layer were studied.The results show that there is a good bonding interface between plasma cladding layer and substrate.With the increase of tungsten carbide particles,the massive irregular structure increases,which is rich in chromium,indicating that the increase of chromium carbide leads to the aggregation of chromium.The hardness of the cladding layer increases with the increase of chromium carbide content.
