Study on corrosion mechanism of copper and inhibitive properties of Domperidone on copper corrosion in different concentration of hydrochloric acid

摘要：

　　In this paper,the corrosion behavior of copper in HCl solution was investigated by electrochemical measurements.Results show that the primary corrosion product is Cu2O in 0.001-0.01 M HCl solution,however,Cu2+ and a small amount of CuCl in 0.1-1 M HCl solution.Domperidone was tested as a corrosion inhibitor for copper in different concentration of HCl solution using potentiodynamic polarization and electrochemical impedance spectroscopy(EIS).The experimental results revealed that domperidone was a cathodic inhibitor in HCl solution,with a maximum achievable inhibition efficiency of 98.5% in 0.01 M HCl tested by EIS.
