On the coating processing, the surface of basal body is purified and rough treated, so the bonding strength of film and basal body increases greatly.

在涂敷工艺上，对基体表面进行净化和粗糙处理，大大提高了膜与基体的结合强度。

C... and in this condition, uniform, harder and tighter with the basal body of the sample can be gained. Moreover, more time, thicker film, but less hardness.

而且随着氧化时间的增加，可以得到相对较大的膜厚度，但膜硬度相对降低。
