摘要
利用全息显微摄影术配合电化学现场测试，研究了酸性介质中铁的阳极溶解、振荡、钝化、去钝化过程以及在氯离子存在下形成孔蚀时电极／溶液界面发生的变化．结果表明：全息显微摄影术可以现场观察电极／溶液界面发生的动态过程，所获得的有关信息可以从固／液界面状态变化的角度深化对电极过程本质的认识．
The holographic microphotography (HM) was coupled with electrochemicalmeasurement to investigate the changes of the electrode-electrolyte interface during the processesof iron anodic dissolution, potentiostatic current oscillations, passivation, depassivation andCl- induced pitting in 0.5mol / L H2SO4 solution. It is concluded that the HM can be used tostudy in-situ the dynamic processes at the electrode-electrolyte interface, and that the information obtained from the interfaces can provide insight into the nature of electrode processes. HM isa completely new experimental method in the study of metallic corrosion.
