摘　　要：通过实验室的周浸腐蚀试验和自然环境的大气暴露试验,结合腐蚀产物的表面分析,研究了Q345钢在室内模拟大气腐蚀环境中的腐蚀规律和在青岛、江津、琼海的大气腐蚀规律,结果表明:在室内模拟加速腐蚀试验和大气暴露试验中,腐蚀规律均符合公式logP=A+Blogt,腐蚀产物一致,主要是α-FeOOH和γ-FeOOH,室内加速试验结果与户外暴露结果有较好的相关性。Through periodically infiltrated corrosion test in the laboratory and atmospheric exposure test in the natural environment in combination with corrosion product surface analysis, the indoor corrosion laws simulating atmospheric environment and corrosion laws in Qingdao,Jiangjin and Qionghai for Q345 steel are studied. The results show that the corrosion laws conform to logP= A ＋ Blogt, that corrosion product of Q345 steel consists mainly of-FeOOH and-FeOOH, and that there exists a good correlativity between indoor accelerated test and outdoor exposure test.
