| 目的 研究海军某型装备壳体结构材料在海洋环境下的腐蚀行为及规律。方法 根据折算出的实验室加速腐蚀试验环境谱，开展了ZL115-T5铸铝合金试验件、ZL115-T5铸铝合金/ C41500海军黄铜接触试验件、模拟实际涂抹黄油试验件以及模拟维护涂抹缓蚀剂试验件的实验室加速腐蚀试验。结果 得到了该型铝合金在不同服役年限及服役状态下的腐蚀形貌、质量、平均腐蚀深度以及腐蚀损伤度变化规律。结论 该型合金在不同服役状态下的腐蚀行为呈现差异化，ZL115-T5铸铝合金与C41500海军黄铜偶合接触会加速铸铝合金的腐蚀，黄油能够在一定程度上抑制电偶腐蚀，但效果并不明显。缓蚀剂能够延缓海洋环境下ZL115-T5铸铝合金腐蚀，其中THFS-10软膜缓蚀剂以及THFS-15长效硬膜缓蚀剂效果较好。 |

| Objective To study corrosion behaviors and laws of a certain naval equipment shell structure material in the marine environment. Methods Accelerated corrosion tests for ZL115-T5 aluminum alloy specimens, ZL115-T5 cast aluminum alloy contacted with C41500 navy brass test pieces, test pieces for simulating the actual structures coated with butter and corrosion inhibitor were carried out in the test room based on the conversion of the laboratory accelerated corrosion test environment spectrum. Results The change laws for corrosion morphology, weight, average corrosion depth and corrosion damage ratio of the aluminum alloy in different service years and service conditions were obtained. Conclusion behaviors of the aluminium alloy under different service conditions are different. The contact of ZL115-T5 cast aluminum alloy and C41500 navy brass can accelerate the corrosion rate of the cast aluminum alloy. The butter can inhibit the galvanic corrosion to a certain extent, but the effect is not obvious. The inhibitor can retard the corrosion of ZL115-T5 cast aluminum alloy in marine environment, and the effect of THFS-10 soft membrane inhibitor and THFS-15 long-term epidural inhibitor is better. |
