摘　　要：综述了在污染大气环境中金属材料初期腐蚀行为和机理研究进展。目前主要采用的研究方法包括试验方法(室外暴露试验、室内加速试验 )、检测方法 (腐蚀速率的测定、腐蚀产物的分析和表面形貌的观察 )和电化学监测方法 ,用原位动态实时监测技术来研究初期腐蚀机理是重点发展的方向 .重点阐述了单个或混合污染物对几种典型金属材料 (铜、锌、钢等 )初期腐蚀行为的影响和作用的研究情况 .The research progress on initial stage of atmospheric corrosion behavior and the relevant corrosion mechanism of metals in pollutant atmospheres were comprehensively reviewed.At the present,the existed main methods for the research may include experimental methods (outdoor exposure and indoor accelerated test),examining methods (determination of corrosion rate,analysis of corrosion products,observation of surface morphology) and electrochemical monitor technology etc.Undoubtedly,the in-situ monitor technology may reprensent a key development trend.The research on the effect of single and mixed pollutants on initial stage of atmospheric corrosion behavior of several typical metals (copper,zinc,steel et al) were emphatically introduced.
