| Abstract: |
| The corrosion behavior of 6061 aluminum alloy in 80 ℃ seawater was studied with laboratory seawater immersion test, pitting potential test and flowing seawater simulation test. It was found that there was pitting corrosion on the surface of 6061 aluminum alloy in normal temperature seawater. In 80 ℃ seawater, the formation of passivation film was easier. It was found from corrosion potential curve in 80 ℃ seawater that passivation and activation changed alternately, the potential was -0.600 V (vs. SCE) when passivation film formation and -1.08 V (vs. SCE) when passivation film brocken. |
