The crystalline defects of metallic substrate can promote the formation of multi-crystal thin films. In contrast, the films on the Si single crystal are basically amorphous; The hardness of films are mainly determined by N concentration. The highest hardnesses of Si〓N〓 and TiN films ware obtained at 1. 1 of N/Si and 0.96 of N/Ti respectively. The hardness of Si〓N〓 film decreased dramatically when the free silicon atoms present.

发现薄膜中N原子百分含量主要受氮离子束流和氮气分压的控制，随着氮离子束流和氮气分压的提高，N/Si和N/Ti原子比增加；膜的组织结构则主要受轰击离子束压和基体种类的影响，高的轰击束压可以抑制薄膜的择优取向，金属基体上的晶体缺陷使薄膜易于形成多晶，而单晶硅上的薄膜基本上为非晶态；薄膜的硬度受氮含量的影响最大。
