钢的大气暴露腐蚀与室内模拟加速腐蚀的相关性
, PP. 70-73
Keywords: 钢,大气腐蚀,加速腐蚀试验
Abstract:
通过大气暴露试验和实验室的浸渍干燥湿润复合循环试验，结合腐蚀产物的表面分析，研究了4种钢在沈阳地区的大气腐蚀规律和模拟大气腐蚀过程的腐蚀规律.结果表明在大气暴露试验和室内模拟加速腐蚀试验中，4种钢的腐蚀产物都具有不同程度的保护性，腐蚀规律可用ΔW=Ktn公式描述，室内外腐蚀试验结果有较好的相关性.采用001mol/LNaHSO3+0.001mol/LNaCl介质为加速剂,通过干湿复合循环试验,可模拟钢在沈阳大气环境中的腐蚀过程，近似推测户外长期暴露试验的结果.
