利用活性燃烧高速燃气(AC-HAVF)喷涂技术在0Cr13Ni5Mo不锈钢上制备了Ni60/WC复合涂层,研究了其微观组织及耐磨耐蚀性能.结果表明:涂层主要由Fe-Ni固溶体以及Cr0.19Fe0.7Ni0.11,WC,M6C(Ni2W4C或Fe3W3C),Cr26C3,CrB2等相组成;涂层与基体结合很好,涂层的孔隙率约为2.5%;WC,M6C,Cr26G3,CrB2等硬质相弥散分布于涂层中,部分区域硬质相达到了200～800 nm;涂层硬度分布不均匀,平均硬度为685HV;涂层具有优异的耐磨耐蚀性,其磨损体积是0Cr13Ni5Mo不锈钢的1/8.8,平均腐蚀速度是0Cr13Ni5Mo不锈钢的1/2;涂层的磨损机理以疲劳磨损为主,弥散分布的硬质相是涂层硬度以及耐磨性提高的主要因素.
