摘要(Abstract)：

采用双辉等离子表面冶金技术在Q235钢表面制备了不同靶材成分比条件下的Ni-Cr合金层,研究了靶材成分与Ni-Cr合金层成分之间的关系,并运用电化学测试技术评价了Ni-Cr合金层的耐蚀性。结果表明:Ni-Cr合金层组织均匀致密,且与基体结合良好。Ni80Cr20靶材制备的Ni-Cr合金层主要物相为Ni2.9Cr0.7Fe0.36奥氏体相,当靶材中Cr含量高于40%时,Ni-Cr合金层主要物相为Cr0.19Fe0.7Ni0.11相和少量Fe-Cr相,且随着Cr元素含量增加,Fe-Cr相的含量逐渐增多,Cr0.19Fe0.7Ni0.11相的含量逐渐减少,而Ni-Cr合金层的耐蚀性和对基体的保护效率也在增强。

关键词(KeyWords)： Ni-Cr合金层;靶材成分;耐蚀性
