Abstract

The process of immersion corrosion on pure magnesium in 0.1 M NaCl solution was investigated by the phase angle. Results show that the peak value of phase angle and responding frequency of peak can be used to characterize the evolution process of corrosion products. It is before 80 min that corrosion products increase on the surface until film layers formed. The theoretical relation between the phase angle and corrosion products was established and the simulated results had a good agreement with the validation experiment data. Moreover, the evolution mechanism of corrosion products was studied by Scanning Vibrating Electrode Technique.

基于相角的纯镁腐蚀产物演变过程分析

通过相角研究了纯镁在 0.1 M NaCl 溶液中的浸泡腐蚀过程。结果表明，相角的峰值和峰值的响应频率可以用来表征腐蚀产物的演变过程。在 80 分钟之前，腐蚀产物在表面增加，直至形成膜层。建立了相角与腐蚀产物之间的理论关系，模拟结果与验证实验数据吻合良好。此外，还利用扫描振动电极技术研究了腐蚀产物的演变机理。
