| 中文摘要: |
| 采用室内海水浸泡试验、 点蚀电位测试、 流动海水模拟试验等方法研究了6061铝合金在80 ℃海水中的腐蚀行为。研究表明， 6061铝合金在常温海水中的腐蚀形貌为点蚀， 在80 ℃海水中6061铝合金表面易形成钝化膜且腐蚀轻微。从80 ℃时的自腐蚀电位曲线可以看出， 铝合金表面钝化-活化过程反复交替进行， 钝化膜形成时其电位约为-0.600 V （vs.SCE）， 钝化膜破裂时其电位约为-1.08 V （vs.SCE）。 |
| 英文摘要: |
| 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. |
