摘　　要：在淡水和海水环境中对纯锌进行实际曝露试验。结果表明,在淡水环境中,锌腐蚀率较小,腐蚀速率随时间延长而减小,生成的腐蚀产物具有一定的保护性能;在海洋环境,锌腐蚀严重,在全浸区1年试样就已腐蚀穿孔,其腐蚀速率随时间延长而减小,但在飞溅区却相反,腐蚀速率随时间延长而增加。Pure Zn was exposed in freshwater and seawater environment and its corrosion behavior was observed. The resuits showed that, in the freshwater environment, the corrosion rate of Zn decrease with time, and the corrosion products have certain protection ability. But in the marine environment, the corrosion of Zn is serious; in immersion zone for one year, the sample had been corrosion perforation, and the corrosion rate decreases with time; while in the splashing zone, the corrosion rate increase with time.
