1 前言由于铜的腐蚀过程不存在析氢现象,因而在不含氧化剂的非氧化性酸中,铜是耐蚀的。但当铜的使用环境中存在氧及其它氧化剂如铁离子(Fe~(3+))、硝酸根离子(NO_3~-)时,就有必要考虑铜的腐蚀及防护了。防止金属腐蚀的一个最重要的方法是在腐蚀性环境中添加有机缓蚀剂。对铜及其合金而言,广泛应用的最佳缓蚀剂是苯并三氮 1 Introduction Copper is corrosion-resistant in non-oxidizing, non-oxidizing, acids because there is no hydrogen evolution in the copper corrosion process. However, it is necessary to consider the corrosion and protection of copper when oxygen and other oxidants such as iron ions (Fe 3+) and nitrate ions (NO 3 -) are present in the copper environment. One of the most important ways to prevent metal corrosion is to add organic corrosion inhibitors in a corrosive environment. The most widely used corrosion inhibitor for copper and its alloys is benzotriazole
