passivation material 钝化物件 ; 钝化物料
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.
在钝化历程中应严酷控制钝化液中氯离子含量，所用钝化用化学质料对氯离子都有限量要求。
