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。 |

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.45steel and No.12duralumin was done under different temperature-humidity environments, and the test results based on different conditions were compared.ResultsThe relationships between corrosion velocity and temperature-humidity environment of the two kinds of metal materials were obtained. Besides, the "corrosion-time" relationships of No.45steel and No.12duralumin under conditions of "40℃, 85%RH" and70℃, 85%RH”were built.Conclusion The acceleration factor of No.45steel and No.12duralumin based on temperature-humidity environment and storage time fitted the anti-power law model. |
