摘要: 锌在ＳＯ_２污染环境中的腐蚀规律王振尧，郑逸苹，刘寿荣（中国科学院金属腐蚀与防护研究所沈阳１１００１５）１前言在我国西南地区，由于地理环境的影响，酸沉降日趋严重．含硫煤燃烧所排放的ＳＯ２造成雨水酸化，酸沉降引起的腐蚀问题受到人们关注．因此，在该地区进行材料的腐蚀研究具有重要的现实意义．ＳＯ。在高湿条件下对大多数金属和合金有强烈的加速腐蚀作用［１］．Ｓｈｅｒｒｙ等［２－４］就高湿条件下低浓度ＳＯ....

Abstract：The corrosion process of zinc in Guiyang and Huitong areas and under the condition of high concentration of SO2 can be described by a formula: △W = Ktn, where △W stands for weight loss, t represents duration of expose, while n and K are constats. The greater the pollution of SO2 and the relative humidity, the more serious the corrosion of zinc. The X-ray diffraction data show that, the corrosion product is mainly composed of sulfates of zinc. The corrosion productproduct formed in SO2-containing environment hinder anodic process of zinc corrosion.
