CORROSION INHIBITORS FOR COPPER AND COPPER ALLOYS.

Abstract

A review of recent literature on corrosion inhibitors for copper and copper alloys is presented. Inhibitors are divided into two categories; (i) inorganic inhibitors, such as chromates, phosphates, and ferrous ions and (ii) organic inhibitors which include heterocyclic organic compounds, i. e. , benzotriazol (BTA) and mercaptobenzothiazole (MBT) and their relative compounds. At present these are the most effective and widely used inhibitors in a variety of systems.
