Abstract

The corrosion inhibition of copper in 0.05mol/L NaHCO 3 in the presence of pyrazole and the synergetic effect of pyrazole with BTA and MBT were studied using cyclic voltammetry techniques and rotating disc electrode. The results showed that the pyrazole was adsorbed on the copper surface and there was a synergetic effect between pyrazole and BTA, but it was not obviously between pyrazole and MBT.
