用电化学方法考察研究了２巯基苯并恶唑（ＭＢＯ） 在３ ％ ＮａＣｌ 溶液中对铜的缓蚀性能。ＭＢＯ 同时抑制阴极和阳极过程。缓蚀效率与ＭＢＯ 浓度、铜样品在含ＭＢＯ 的溶液中预浸泡时间以及该溶液的腐蚀性有关。当铜样品在ＭＢＯ饱和（１ｍｍｏｌ／Ｌ） 的３ ％ ＮａＣｌ 中处理２０ｈ 以上，缓蚀率达到约９９ ％ ，而处理介质不含ＮａＣｌ 时则缓蚀率低得多。因此，ＭＢＯ 缓蚀膜的生成与铜本身的腐蚀过程有关。
The electrochemical corrosion inhibition of 2mercaptobenzoxazole (MBO) in 3% NaCl solution was studied. MBO suppresses both cathodic and anodic processes. The corrosion inhibition efficiency is related to the MBO concentration, the pre-soaking time of the copper sample in the MBO-containing solution, and the solution’s corrosiveness. When copper samples were treated with MBO saturated (1mmol / L) 3% NaCl for more than 20h, the corrosion inhibition rate was about 99%, but the corrosion inhibition rate was much lower in the treatment medium without NaCl. Therefore, the formation of MBO corrosion film and copper itself is related to the corrosion process.
