| 摘 要： | 目的研究45号钢和12号硬铝的温、湿度加速腐蚀情况。方法在不同的温、湿度环境下开展45号钢和12号硬铝的加速腐蚀试验，并将不同条件下的试验结果进行对比。结果得到了45号钢和12号硬铝的腐蚀速度与温、湿度条件的关系，获得了45号钢和12号硬铝分别在“40℃，RH为85％”和“70℃，RH为85％”2种温、湿度环境下的“腐蚀速度-时间”函数关系。结论45号钢和12号硬铝在温、湿度环境下的加速因子与贮存时间呈逆幂率关系。

| Abstract: | Objective To discusses the accelerated corrosion of No.45 steel and No.12 duralumin based on different temperature-humidity environments. Methods Accelerated corrosion test of No.45 steel and No.12 duralumin was done under different temperature-humidity environments, and the test results based on different conditions were compared. Results The relationships between corrosion velocity and temperature-humidity environment of the two kinds of metal materials were obtained. Besides, the ＂corrosion-time＂ relationships of No.45 steel and No.12 duralumin under conditions of ＂40℃, 85%RH＂ and 70℃, 85%RH＂ were built. Conclusion The acceleration factor of No.45 steel and No.12 duralumin based on temperature-humidity environment and storage time fitted the anti-power law model. |
