摘　　要：用化学镀方法在钛合金Ti-6Al-4V表面制备了Ni-P合金镀层,并在不同温度下对合金镀层进行了热处理;通过扫描电镜(SEM)、X射线衍射仪(XRD)、硬度测试及摩擦磨损试验研究了热处理温度对Ni-P合金镀层相组成和显微硬度及耐磨性能的影响。结果表明:在400℃热处理2h后,Ni-P合金镀层的结构致密均匀,其显微硬度最高,达到910HV,耐磨性能也最好。Ni-P alloy coating was prepared on the surface of titanium alloy Ti-6 Al-4 V by electroless deposition method,and heat-treated at different temperatures.The effects of heat treatment temperature on phase composition,micro-hardness and wear resistance of the Ni-P alloy coating were investigated by scanning electron microscopy（SEM）,X-ray diffraction（XRD）,hardness testing and friction-wear testing.The results show that the Ni-P alloy coating heat-treated at 400℃for 2 hhad a compact and uniform structure,the largest micro-hardness of 910 HV and the best wear resistance.
