摘要(Abstract)：

采用化学镀工艺在不锈钢表面获得了Ni-Cr-P合金镀层。研究了Ni-Cr-P非晶态合金膜随热处理温度升高,其结构以及显微硬度和耐蚀性的变化规律,并对变化的原因进行了分析。结果表明,镀态Ni-Cr-P为非晶态镀层,200℃热处理开始晶化,到400℃时Ni3P晶化比较完全,800℃时Ni3P完全分解,生成含Ni、Cr、Fe的合金膜的Cr2Ni3和FeNi2P相。其显微硬度随热处理温度升高而升高,500～600℃之间显微硬度略有下降,600～700℃又随着热处理温度的升高而略有升高,700℃后显微硬度略有下降;合金膜的耐腐性在热处理温度200～400℃间变化较小,500℃热处理后其耐腐蚀性下降厉害,600～700℃随着热处理温度的升高其耐腐蚀性又略有升高,800℃后由于Ni3P的分解其耐腐蚀性又急剧下降。
