通过大气暴露试验和间歇式盐水喷雾试验 ,并对腐蚀产物的形貌和组成进行分析 ,研究铜在污染环境中的大气腐蚀行为。实验结果表明 ,大气湿沉降和 Na HSO3 对铜的腐蚀影响是显著的 ,铜的腐蚀规律可用W=A+ Bt公式描述
Atmospheric corrosion behavior of copper in polluted environment was studied by atmospheric exposure test and intermittent salt water spray test. The morphology and composition of the corrosion products were analyzed. The experimental results show that the atmospheric wet deposition and Na HSO3 affect the corrosion of copper significantly, and the corrosion law of copper can be described by W = A + Bt formula
