摘　　要：２—巯基苯并噻唑对ＮａＣｌ溶液中铜的缓蚀行为旷亚非，陈曙，林志成（湖南大学长沙４１００８２）１引言苯并三氮峻（ＢＴＡ）和２一流基苯井喷吐（ＭＢＴ）是目前广为使用的铜及铜合金的有效缓蚀剂，但关于ＭＢＴ对铜的缓蚀机理以及ＭＢＴ在Ｃ［ｌ／溶液界面的吸附规律...Abstract The corrosion inhibition effect of 2-mercaptobenzothiazole (MBT) was investigated by weight loss,interficial capacitance, potentiodynamic polarization and XPS techniques. It was found that MBT is a goodinhibitor for copper and that both anodic and cathodic processes are inhibited. The double capacitancedecreases with increasing concentration of MBT. Little MBT is detected in the film on copper surfaceand the depth of MBT adsorption layer is only 20￣40A. The results indicate that corrosion of copper isinhibited through adsorbing MBT on the Cu/solution interface. The adsorption of MBT follows modified Bockris-Swinkels isotherm. Some thermodynamic parameters related to the adsorption were evaluated.
