| Abstract: | In this paper ,it makes some correction on the existing nonlinear model of corrosion,come up with a more character and practical model of corrosion,and the actual detection data show that the modified model can true reflect the whole process of metal cor-rosion,and compare the resistance deterioration law and the time -dependent reliability of the component of the hydraulic steel gate by the existing model and the modified model,which lays the foundation for the study of reliability of Hydraulic steel gate structure. |

| Keywords: | corrosion rate resistance deterioration JC method reliability index |
