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.
