摘要：

The corrosion inhibition behavior of pyrazole and the synergistic effect with benzotriazole (BTA) or 2-mercaptobenzothiazole (MBT) on the corrosion of copper in 0.05 M NaHCO3 solution were studied using cyclic voltammetry techniques (CV) and rotating disc electrode (RDE). The results showed that the adsorption of Pz on the surface of copper obeyed Frumkin adsorption isotherm, and the anodic dissolution of copper is determined by the electrochemical step. There was a synergetic effect between pyrazole and BTA, but it was unconspicuous between pyrazole and MBT.
