There are intergranular corrosion cracking in stainlesssteel, all of which have negative effects on the passive film on the surface of stainlesssteel plate.
还有不锈钢内部的晶间腐蚀开裂，所有这些，对不锈钢板表面的钝化膜都发生破坏作用。
2
The passive film may be augmented by chemical treatments that provide an oxidizing environment for the stainlesssteel surface.
通过为不锈钢表面提供一个氧化环境的化学处理，钝化膜可以得到增强。

This oxide layer is what renders the stainlesssteelpassive and non-reactive to corrosion.
