B10合金与某高强钢是舰船海水系统的两种典型舰船结构材料，通过电化学测试考察了两种材料的电偶腐蚀倾向，通过模拟腐蚀试验研究了其在静态和动态海水中的电偶特性，通过串联不同阻值电阻的模拟电绝缘仿真计算，评估了两材料偶合的电绝缘判据。结果表明：B10合金与某高强钢在海水中有较强的的电偶腐蚀倾向，偶接后高强钢作为阳极，腐蚀加速；动态海水环境中电偶的腐蚀加速作用更加明显；仿真结果显示，B10合金与高强钢电偶对之间的绝缘电阻高于4 kΩ时，可有效控制电偶腐蚀。

B10 copper alloy and a high-strength steel are two typical ship structural materials for ship seawater systems. The galvanic corrosion tendency of the two materials was investigated by electrochemical tests,the galvanic characteristics in static and dynamic seawater were studied by simulated corrosion tests,and the electrical insulation simulation of the two materials was evaluated by simulating the electrical insulation simulation calculation using connecting resistors with different resistance values. The results show that B10 alloy and the high-strength steel had strong galvanic corrosion tendency in seawater,after the two materials were connected, the high-strength steel acted as an anode and the corrosion was accelerated. The corrosion acceleration of galvanic couples in dynamic seawater environments was more pronounced. The simulation results show that the galvanic corrosion could be effectively controlled when the insulation resistance between the B10 alloy and the high-strength steel was higher than 4 kΩ.
