Abstract Inhibition for copper alloy in high concentration chloride solution has been explored with in-situ graze ellipsometry and linear sweep voltammetry(LSV) technology. The results show that the change of parameter behind of current change and the shift of corrosion productions into solution were blocked by the BTA layer. With the corrosion production accumulated, the increase of overpotential on anode was necessity, and potential difference of corrosion reaction was decreased.Thus the rate of corrosion reaction was delayed and the corrosion resistance of copper alloy was increased.

Key words: Copper Alloy Benzotriazole ellipsometry CaCl2
