摘要：
It has been found that in hydrocarbonate-chloride solutions (pH = 8.4) benzotriazole inhibits copper pitting corrosion. Comparative results obtained on stationary and rotating disc electrode have shown that rotation stabilizes the metal/electrolyte systems. Under drastic hydrodynamic conditions, the benzotriazole concentration required for full suppression of copper pitting corrosion was reduced 10-fold on a rotating disc.
