典型大气环境中钢材的腐蚀行为研究进展

Review on Corrosion Behavior of Steel in Typical Atmospheric Environment

大气腐蚀是钢铁材料常发生的一类腐蚀,近年来,研究了不同大气环境中钢铁材料的腐蚀行为。综述了大气组分中的水、二氧化碳、硫化物和氯化物对钢材的腐蚀速率、腐蚀层形貌和腐蚀产物的影响;分析了海洋大气环境和含硫、氧污染物大气环境中钢材的腐蚀行为。

Atmospheric corrosion is the most common type of corrosion in steel materials.In recent years,the corrosion behavior of the steel materials in different atmospheric environments were studied.The effects of water,carbon dioxide,sulphide and chloride in atmospheric components on the corrosion rate,corrosion layer morphology and corrosion products of steel materials,were reviewed.The corrosion behavior of the steel in marine atmospheric environment and pollutant atmospheric environment with S and Cl were analyzed.
