摘　　要：介绍了微通道换热器中存在的腐蚀问题,概述了包括冷却剂、合金相间电位差、大气污染物等腐蚀诱因和机理,并总结了缓蚀剂添加和基材表面处理等腐蚀控制手段;阐述了诸如化学镀、阳极氧化、化学转化、溶胶-凝胶处理等3003铝合金基材的表面防护技术,为耐蚀铝合金微通道换热器的开发和生产提供参考。Microchannel heat exchangers of Al-alloy are the important component for air conditioner,of which the primary material is 3003 Al-alloy.In practical applications,the Al-alloy is suffered from corrosion and then results in the heat exchanger failure.This paper firstly introduces the corrosion problems existing in microchannel heat exchangers,then reviews the corrosion causes and influencing factors,such as coolants,micro-galvanic corrosion of the alloy and air pollutants etc.,and summarizes corrosion control methods such as inhibitors and surface treatments.Finally elaborates some surface treatment techniques developed for 3003 Al-alloy,including electroless plating,anodizing,chemical conversion,solgel treatment etc.,which probably provide references for the development and production of corrosion-resistant microchannel heat exchangers of 3003 Al-alloy.
