摘要
8108缓蚀剂的主要成分是硝酸盐。经过静态浸泡,半稳态动电位阳极极化曲线的测定,湿热实验和使用考核,对8108的缓蚀作用进行了研究。结果表明8108的缓蚀效果不低于传统使用的0.3%重铬酸钾溶液。初步探讨了8108的缓蚀机理,认为它属于阳极钝化型缓蚀剂。
Inhibitor 8108, which is mainly comprised of nitrate has been investigated by potentiodynamic polarization, static immersion and humidity test. Trial examination has been also conducted. The results showed that the inhibition effectiveness of 8108 is not inferior to that ot 0.3% K_2Cr_2O_7 solution and it may be used instead of chromate for aluminium alloy in near-neutral solution. An approach has been made in terms of inhibition mechanism and 8108 is considered as an inhibitor of anodic passivation type.
