This structure forms the passivation layer against corrosion and wear. The optimum layer against wear improves the resistance of material surface in corrosion, wear and fatigue extremely.
这种结构形成了抗磨损的优化表面层和抗腐蚀的钝化层，明显改善了材料表面抗磨损、抗疲劳和抗腐蚀特性。

Should be strict control in the passivation process of chlorine ion in the passivation solution, the passivation with chemical material used for chloride ions are limited.
