1) transpassivation
过钝化
1.
The activation time of transpassive film formed on 304 stainless steel in the transpassivation region is almost 2 magnitude of order higher than that of passive film formed in passivation region and its breakdown potential is strikingly improved if post-treatment is conducted in a McO_4~(2-) containing solution.
在载波钝化膜研究中,我们注意到能使钝化膜稳定性显著提高的载波幅值正半周都进入到不锈钢过钝化区中,因而推断在过钝化区生成的过钝化膜在低电位区自然状态下的稳定性也可能会有所提高。
2) desensitizing RDX of over shelf life
过期钝化RDX
1.
A kind of methods to recycling desensitizing RDX of over shelf life was introduced in this article.
介绍了一种过期钝化RDX的资源化再利用方法,采用水悬浮煮洗工艺,通过加入表面活性剂添加剂,使钝化RDX表面的钝感剂剔除。
3) transpassive potential
过钝化电位
4) transpassive corrosion
过钝化腐蚀
1.
Ultra-low-carbon austenitic stainless steels have the tendency of transpassive corrosion and intergranular attack in strongly oxidizing nitric acid(concentrated nitric acid,presence of oxidizing species).
超低碳Cr-Ni奥氏体不锈钢在含强氧化性离子的硝酸溶液中会发生过钝化腐蚀和晶间腐蚀,而高硅不锈钢在强氧化性浓硝酸中具有优良的耐蚀性。
5) transpassivation current density
过钝化电流密度
6) H_2O_2 passivation process
过氧化氢钝化工艺
1.
<Abstrcat> The conventional H_2O_2 passivation process is difficult to master.
传统的过氧化氢钝化工艺较难掌握,钝化条件比较苛刻,钝化效果一般,还容易出现一种褐色不明附着物。
补充资料:过钝化电流密度
分子式:
CAS号:
性质:在某一很正的电位值下,金属从钝态重新转变为活态,对应这一过钝化电位的电流密度称为过钝化电流密度。它的数值与金属性质和腐蚀介质性质(包括组成、浓度、pH值、温度)有关。
