利用横截面电镜样品,对Ni基体磁控溅射离子镀Al膜进行了透射电镜观察。研究了不同工艺条件下镀膜的组织形态,相结构以及相分布。镀覆5min时,在Ni基体和镀Al膜交界处,发现一个Al-Ni系中迄今未见报道的未知相。经电子衍射分析其为体心四方点阵,a=b=0.588nm,c=0.480nm。研究了随时间变化的镀膜组织结构变化情况。

A new phase was found at the interface between Al film and Ni substrate when the time of ion-plating reaches 5 min.It was identified to be body centered tetragonal lattice with the constants a=b=0.588 nm,c=0.480 nm.The variation of microstructure and phases with the ion-plating time were observed.Based on these results,the ion-plating film formation mech- anism has been also discussed.

The composite coating of(N~++IP)-TiN was prepared by ion-plated TiN film onto ion-nitrided case on the low carbon steel substrate.The microhardness measurement along in- terface between IP-TiN coating and substrate was detected as a moderate decrease in magni- tude with increase of distance from the coating surface.This seems due to the occurrence of ion nitride case,ε-Fe_3N-Fe_2N and Fe_4N phases,along the interface.
