Influence of pH and Chlorides on Electrochemical Behavior of Brass in Presence of Benzotriazole

This paper describes an investigation of the corrosion behavior of Cu37Zn brass in borate buffer solutions at various pH, in the presence of benzotriazole, with and without the addition of chloride ions. The values of anodic current densities are considerably smaller in borate buffer solutions with the addition of benzotriazole compared with those in the inhibitor-free solution. The study analyses the electrochemical behavior of Cu37Zn brass after various times of brass exposure to solution of benzotriazole, as well as its’ behavior in solution of benzotriazole of various concentrations.
