摘要
对采用多弧镀方法在ＣＨ７５热作模具钢表面沉积的ＴｉＮ与（Ｔｉ，Ａｌ）Ｎ膜的抗氧化性与抗热疲劳性能进行了研究．（Ｔｉ，Ａｌ）Ｎ膜具有比ＴｉＮ膜高的硬度、韧性、高温抗氧化性和抗热疲劳性能，分析表明，由于Ａｌ的选择性氧化形成的Ａ１＿２Ｏ＿３保护层，是（Ｔｉ，Ａｌ）Ｎ膜具有优良高温抗氧化性能和抗热疲劳性能的原因。
The oxidation and thermal fatigue resisting ability of TiN and(Ti,Al)N films depositedby multi- arc ion- plating on hot work steel type CH75 is studied.The hardness,tQughness,oxidation resistance and thermal fatigue of(Ti, Al)N films at high temperatures are superiorto those of TiN films. It is shown that the better performance of (Ti,Al)N films is attribut-ed to the formation of a protective layer of Al2O3 formed by selective oxidation of Al.
