| 目的 研究三种流速下微弧氧化钛和高强钢的电偶腐蚀行为。方法 在面积比为1:1情况下进行1，3，7 m/s流速下的电化学测试和电偶腐蚀试验研究。结果 随着流速的增大，偶合电流、总腐蚀速率和电偶腐蚀速率增大。当流速为7 m/s时，高强钢总腐蚀速率和电偶腐蚀速率分别达到8.64 mm/a和0.39 mm/a，与静态相比分别增大146倍和15.6倍，与1 m/s流速下相比分别增大8.6倍和5倍。结论 在面积比为1:1时，冲刷腐蚀速率远大于电偶腐蚀速率。 |

| Objective To study the galvanic corrosion behavior between TA2 (micro arc oxidation) and high strength steel under three flow rates. Methods The electrochemical test and the galvanic corrosion test were studied in 1 m/s, 3 m/s and 7 m/s of sea water under area radio of 1:1. Results The galvanic current, total corrosion rate and galvanic corrosion increased with the increase of flow rate. When the flow velocity increased to 7 m/s, total corrosion rate and galvanic corrosion rate of high strength steel reached 8.64 mm/a and 0.39 mm/a respectively, it increased by 146 times and 15.6 times respectively compared with static state, while it increased by 8.6 times and 5 times respectively compared with the velocity of 1 m/s. Conclusion The area ratio is 1:1, and the erosion corrosion rate is far greater than the galvanic corrosion rate. |
