摘　　要：以球墨铸铁为研究对象,通过在球墨铸铁表面热喷涂镍60,并对热喷涂镍60后的球墨铸铁试样进行不同温度的热处理,以观察球墨铸铁与镍结合层的组织变化。结果表明:球墨铸铁等离子喷涂镍60后对其进行不同温度的热处理,其组织形貌有细微改变。但是球墨铸铁与镍结合层没有因为温度的影响而脱落。Taking nodular cast iron as subject,heat treatment under different temperature was carrieed out on nodular cast iron sample after coating with hot Ni60,so as to observe microstructure change of combined course of nodular cast iron and nickel.The results show that microstructure morphology of nodular cast iron is slightly changed after heat treatment at different temperature after plasma-spray of nickel 60,but combined course of nodular cast iron and nickel doesn’t fall off due to impact of temperature.
