Effect of Benzotriazole on Oxidation Behavior in Pure Copper

Abstract

In this study, we investigated the effects of the corrosion inhibitor benzotriazole (BTA) with the chemical formula C₆H₅N₃,on the oxidation behavior of copper through microstructure analysis. Our results demonstrate that BTA on copper decreased oxidation rate and alters the morphological characteristics of the copper oxide during oxidation. The biocidal ability of copper was found to be unaffected by the presence of BTA. Our findings suggest that the stability of the interface between copper and its oxide, Cu₂O, is primarily determined by atmospheric pressure rather than the presence of BTA during the oxidation process. This study provides valuable insights into the role of BTA in the oxidation behavior of copper, which can have implications for various applications.
