| Abstract: |
| 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. |
