Abstract

An in situ hydrogen gas detection system was developed to determine the hydrogen evolution rate (HER) from Mg during anodic potentiodynamic polarization (APP) curve measurement. The system, which is composed of an electrochemical cell and a gas-chromatograph, allows for successive determination of HER during the APP curve measurement because evolved gas was delivered directly to the gas-chromatograph using Ar carrier gas. As the HER could be determined every 104 s after starting APP measurement from corrosion potential, the HER could be plotted against polarization potential. It was confirmed that the HER was correlated with anodic current values in the APP curve.
