【摘要】 综述了数十年来苯并三氮唑(BTA)对铜缓蚀机理的研究成果,重点介绍了酸性、近中性、碱性及含氯介质中BTA所形成缓蚀膜的结构与组成、缓蚀作用类型:BTA通过在铜表面形成一层保护膜而抑制铜腐蚀,缓蚀膜的形成受到氧气、阳极极化、BTA浓度和pH值的影响,高BTA浓度及高pH值均有利于缓蚀膜的形成。更多还原

【Abstract】 A review was provided of the research progress of the inhibition mechanism of benzotriazole (BTA) as corrosion inhibitor for copper. The surface structure and composition as well as the corrosion inhibition type of protective films of BTA formed in acidic medium, nearly neutral medium and alkaline medium were highlighted. It was pointed out that BTA functioned to prevent Cu from corrosion by forming protective films on Cu surface. The formation of BTA protective films was affected by oxygen, anodic polarization, BTA concentration and pH value, while elevating BTA concentration and pH value favored the formation of the BTA protective films.更多还原
