【 摘 要 】

The corrosion of copper - nickel alloy in hydrochloric acid was investigated at different temperatures, inhibitor concentrations, and corrosive solution rotation rates. Weight loss technique was used to evaluate the corrosion rate data. Tetraethylenepentamine was used as organic corrosion inhibitor, while hydrochloric acid was the corrosive solution. Different parameters, such as inhibitor efficiency, activation energy were obtained. Corrosion rate increased with both temperature and acid rotation rate, while it decreased with increases of Tetraethylenepentamine concentration. Maximum inhibitor efficiency was at lower level of temperature, acid rotation rate and higher level of inhibitor concentration.
