【摘要】 在辽宁省范围内约等距离地设置了192处挂片点,进行锌及铜、铝有色金属材料的大气暴露试验。两年后测量不同地点的腐蚀率,绘制成辽宁省大气腐蚀图。此外,根据各试验点的气象与大气污染数据,腐蚀形貌和腐蚀产物分析结果,讨论了锌等材料的大气腐蚀规律。更多还原

【Abstract】 A two-year survey of atmospheric corrosion of Zn in Liaoning province of China has been made at 192 test sites, the results of the field exposure have been analyzed in combination with environmental data. Corrosion maps of Liaoning area have been drawn. The models are proposed to describe correlation of corrosion rates and the environment parameters, among which, the time of wetness and SO₂ concentration seem to be the most important factors for determining atmospheric corrosion rates of Zn.更多还原
