| Abstract: |
| Galvanic corrosion of Ti8LC titanium alloy coupled with 7710, ZL59 aluminum alloys and 30CrMnSiA high strength steel was studied through measurement of open circuit potential and galvanic current. Galvanic corrosion behavior of the three couples was studied before and after protecting treatment and their galvanic corrosion sensitivity was evaluated. The results show that when Ti8LC titanium alloy couples with 7710 aluminum alloy,ZL59 aluminum alloy, 30CrMnSiA high strength steel, there is serious galvanic corrosion, so the alloy must be suface protecting treated befor use; Surface treatment and organic coating can prevent the galvanic corrosion of titanium alloy coupled with aluminum alloys and high strength steel. |
