| 英文摘要 | The anodic hydrogen evolution (AHE) on Mg, MgZn2 (eta-phase), Al4Cu2Mg8Si7 (Q-phase), and Mg2Si (beta-phase) intermetallic compounds has been investigated using hydrogen evolution technique and customized polarization schemes. Results show that at constant applied anodic current densities, the hydrogen evolution rates on pure Mg and MgZn2 are much higher than those of Q-phase and Mg2Si, indicating AHE is not very pronounced on Q-phase and Mg2Si. After anodic galvanostatic polarization, an obvious enhanced cathodic activity was observed for Mg, MgZn2, and Al4Cu2Mg8Si7 with no obvious change for Mg2Si. The stepped galvanostatic-potentiostatic tests reveal that pure Mg has the highest degree of cathodic activity enhancement with the increase of applied anodic current density, followed by Q-phase and MgZn2, while no obvious change of cathodic activity was noted in the case of Mg2Si. No single model was seen to be suitable for explaining the observed AHE of all the electrodes at the same time. However, the "incomplete film univalent Mg+ ion mechanism" and the "enhanced catalytic activity mechanism" can explain the observed experimental phenomena in many cases. |
