| 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.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. |
