摘要

以Ti粉、C粉、TiN粉和Ni60A粉末为原料

利用氩弧熔覆技术在16Mn钢基材表面成功制备出Ni基增强相复合涂层

应用OM、SEM、XRD对复合涂层的显微组织和物相进行了分析。结果表明

复合涂层物相由TiC、TiN颗粒

γ-Ni奥氏体枝晶和枝晶间的Cr23C6共晶组织组成。涂层的硬度（HV0.2）达到900

较基体16Mn钢提高了3倍多;相对耐磨性较基体16Mn钢提高了8倍。

Abstract

Ni-based reinforced composite coating was prepared successfully on the surface of 16Mn steel with the pre-alloyed powder of Ti

TiN and Ni60Aby means of argon arc cladding technique.The microstructure and phase constituent were investigated using OM（optical microscope）、SEM（scanning electron microscopy）and XRD（X-ray diffraction）.The results show that the composite coating is composed of TiC、TiN

γ-Ni and M23C6particles.The microhardness can reach 900HV0.2

which is 3times higher than that of 16Mn steel.The relative wear resistance of coating is about 8times higher than that of 16Mn steel substrate.
