摘要

研究了 2524-T3 铝合金在不同环境因素的海洋环境中的大气腐蚀及其导致的机械性能退化。2524-T3 铝合金在热带海洋大气中的腐蚀最为严重，这归因于最高的温度、湿度、降雨量、Cl-沉积率和最长的潮湿时间。EIS 结果与腐蚀演变过程密切相关。以伸长率、面积减少率和拉伸强度为指标的降解敏感性与平均腐蚀引起的表面缺陷深度（D′ave）相关，而弹性模量则与最大腐蚀穿透深度（Dmax）相关。

Atmospheric corrosion and mechanical property degradation of 2524-T3 aluminum alloy in marine environments

Atmospheric corrosion and the resulting mechanical property degradation of 2524-T3 aluminum alloy in marine environments with different environmental factors are investigated. 2524-T3 aluminum alloy exhibits the most severe corrosion in tropical marine atmosphere, attributed to the highest temperature, humidity, rainfall, Cl^- deposition rate, and the longest time of wetness. The EIS results are closely related to the corrosion evolution process. The degradation sensitivity indexed by elongation, reduction-in-area, and tensile strength is correlated with the average corrosion-induced surface defect depth (D′_ave), while the elasticity modulus is related to the maximum corrosion penetration depth (D_max).
