| Abstract: |
| 9kinds of different composition of sacrificial anodes were selected to test the electrochemical capacity according to the request of CP technical regulation for some jacket, then some kinds of chemical composition are screened out finally. Further macroscopic and microscopic morphology analysis and EDS analysis on etch-pit was executed, the mechanism of the relevant alloy element was discussed in this article. |
