| Abstract: | The corrosion of the weathering steel and carbon steel were investigated by the exposure tests in marine atmosphere of Shanghai area. By the analysis of the metallographical observation and EPMA aalysis, the morphology of corrosion products and distribution of alloying elements were studied. Based on the EIS display of both carbon steel and weathering steel, the corresponding equivalent circuits of steels in marine atmosphere were proposed. Furthermore, the regression analysis of corrosion data were discussed to get the relationship between corrosion depth and time, results showed that atmospheric corrosion of steels could be predicted. |
| Keywords: | weathering steel atmospheric corrosion exposure testing |
