本文采用失重法和电化学测试技术研究了SH-707酸洗缓蚀剂对20号钢腐蚀性能的影响,用渗氢技术考察了氢在基体金属中的扩散行为,并用载波扫描法测定了缓蚀剂的吸附电位范围。根据实验结果讨论了SH-707的缓蚀作用。
In this paper, the effects of SH-707 pickling corrosion inhibitor on the corrosion resistance of 20 # steel were studied by using weight loss method and electrochemical testing technique. The diffusion behavior of hydrogen in the matrix metal was investigated by hydrogen permeation technique. And the carrier- Etch adsorption potential range. Based on the experimental results, the corrosion inhibition of SH-707 was discussed.
