The inhibition mechanism for BTA and CBTME on copper corrosion in the solution was found to be similar each other, by which a protective film is formed through the triazole ring. The substituent group ( -COOCH 3 ) of CBTME plays the role in the inhibition effect due to steric hindrance. A combination of BTA and CBTME showed a synergistic effect and the inhibition mechanism remained the same as individual species.展开更多
