Abstract

As a promising material for marine engineering, the insufficient corrosion resistance of manganese aluminium bronze (MAB) alloy when exposed to the marine environment may limit its application. In the present work, micro-arc oxidation (MAO) of MAB alloy was conducted in an aluminate-based electrolyte with the influence of ultrasonic vibration (UV) examined. A porous ceramic film has been successfully produced on MAB via MAO, which exhibits dramatic increases in both film thickness and compactness after the introduction of UV. As a result, the ceramic film produced by ultrasound-assisted MAO (UMAO) exhibits an enhanced corrosion resistance relative to that via MAO, which also possesses a desired antifouling capability. Hence, the present work illustrates the influence of UV on the MAO behaviour of non-valve alloys and, more importantly, provides theoretical guidance for related surface modification strategies in marine engineering.

超声波振动对锰铝青铜微弧氧化行为的影响

作为一种很有前途的海洋工程材料，锰铝青铜（MAB）合金在海洋环境中的抗腐蚀性不足可能会限制其应用。本研究在铝酸盐电解液中对锰铝青铜合金进行了微弧氧化（MAO），并考察了超声波振动（UV）的影响。通过 MAO 在 MAB 上成功制备了多孔陶瓷膜，在引入紫外线后，陶瓷膜的厚度和致密性都有显著增加。因此，通过超声辅助 MAO（UMAO）制备的陶瓷膜比通过 MAO 制备的陶瓷膜具有更强的耐腐蚀性，同时还具有理想的防污能力。因此，本研究说明了紫外线对非阀合金 MAO 行为的影响，更重要的是，为海洋工程中的相关表面改性策略提供了理论指导。
