摘要

基于飞机油箱舱内的铝合金在油箱积水环境中发生的腐蚀损伤问题,通过研究腐蚀形貌、最大点蚀坑深度、最大点蚀坑开口面积、表面腐蚀损伤度、交流阻抗响应等变化,分析了温度对2A12铝合金在模拟油箱积水环境中初期腐蚀行为的影响。研究发现,最大点蚀坑深度、开口面积、表面腐蚀损伤度都随着温度的升高而增加,特别当温度升高到65℃和75℃时,腐蚀严重加剧,各项评价指标显著增大。在25、35、45、55℃模拟油箱积水环境中,最大点蚀坑深度及开口面积随时间的关系呈现幂函数变化规律,而在65℃、75℃时,其遵循最小二乘法多项式拟合。电化学交流阻抗谱测试结果表明,2A12铝合金在3个特征温度(常温25℃、中温55℃及高温75℃)下的腐蚀速度快慢为V_75℃ > V_55℃ > V_25℃。

Abstract

Aluminum alloy corrosion in airplane tank water is a serious problem. The influence of temperature on the initial corrosion behavior of aluminum alloy 2A12 in a simulated tank water environment is studied by observing the corrosion morphology, maximum pitting corrosion depth, maximum pitting corrosion area, surface corrosion damage ratio, EIS, etc. The results indicate that pitting corrosion depth, pitting corrosion area and surface corrosion damage ratio increase with increasing temperature. In particular, at temperatures 65℃ and 75℃, corrosion speed increases dramatically. In the simulated tank water of 25, 35, 45 and 55℃, the variation in maximum pitting corrosion depth and area with time all fit well withthe power function. At temperatures 65℃ and 75℃, they both fit well with the least square polynomial fitting. In addition, EIS indicates that corrosion rate in simulated tank water of three typical temperatures (25, 55, 75℃) increases with temperature increase.

Key words： aluminum alloys; simulated tank water; pitting corrosion depth; pitting corrosion area; corrosion damage ratio
