摘　　要：铜合金在海洋工程、交通运输和航空航天等领域具有广阔的应用前景。由于服役环境复杂,除了要求优异的力学性能外,对铜合金的耐腐蚀性也提出了很高的要求。综述了铜合金电化学腐蚀的研究现状,重点分析了外界环境因素(温度、pH值等)和合金元素(Fe、Mn等)对铜合金腐蚀电位、腐蚀电流、腐蚀类型以及腐蚀产物等的影响规律和机制,以期为后续铜合金耐蚀性能的优化提供参考。Copper alloys have broad application prospects in the fields of marine engineering,transportation and aerospace.Due to the complex service environment,in addition to excellent mechanical properties,the corrosion resistance of copper alloys is also highly required.Therefore,the research status on electrochemical corrosion of copper alloys were reviewed,and influence law as well as mechanism of external environmental factors(temperature,pH value,etc.)and alloying elements(Fe,Mn,etc.)on the corrosion potential,corrosion current,corrosion types and corrosion products of copper alloys were emphasized in order to provide reference for the subsequent optimization of the corrosion resistance of copper alloys.
