摘要

目的开展海空跨界质装备复杂海洋环境适应性设计,并对设计方案进行环境试验验证考核。方法针对海空跨界质装备面临长期被海水反复浸泡的环境,设计干湿交替的表层海水腐蚀自然试验方法,提出6种不同的涂层方案,对比这些涂层方案在表层海水自然试验90 d中的腐蚀结果。结果通过对样板试验后外观、光泽度、附着力,低频阻抗模值等方面的分析对比评价,确定了污损脱附型防护涂层方案。结论试验样板搭接的设计方案可以更加真实地模拟装备的实际状态,可以更加直观地呈现不同材料间的电化学腐蚀情况。干湿交替的试验方案有利于快速暴露腐蚀结果,通过试验选择的涂层和工艺方案也为后续海空跨介质类装备的耐海水腐蚀防护提供了设计思路和方法。

Abstract

The work aims to conduct the complex marine environmental adaptability design for sea-air cross-medium equipment and validate the design through environmental testing. To address the long-term repeated seawater immersion environment faced by sea-air cross-medium equipment, a natural test method with alternating wet-dry surface seawater corrosion was designed. Six different coating schemes were proposed and compared through 90-day natural surface seawater exposure tests. By analyzing the appearance, glossiness, adhesion, low-frequency impedance modulus, and other parameters of the post-test sample, the fouling-release protective coating scheme was determined as the optimal. The designed test sample connection method effectively simulates actual equipment conditions, visually demonstrating electrochemical corrosion between different materials. The alternating wet-dry test method accelerates corrosion exposure, and the selected coating and process scheme provides valuable design ideas and methods for corrosion protection of future sea-air cross-medium equipment.
