BTA complex inhibition mechanism inhibitor for copper

Benzotriazole is a kind of common and effective corrosion inhibitor on copper alloy.After processing by benzotriazole,it is formed a complex of protective film by benzotriazole as well as Cu+ on the surface of copper,and hinder ed the further corrosion of copper.Nowadays,scholars exploitated benzotriazole compounded corrosion inhibitor because of it not very ideal of single benzotriazole's slow-release effect.It was possess ed better synergistic effect and promoted interface interaction each other.Meanwhile,it was possessed multivariate protective film to generate synergistic protective effect.It was introduced the inhibition mechanism of benzotriazole and benzotriazole compounded corrosion inhibitor in this article.
