飞机用铝合金腐蚀行为和腐蚀预测研究现状及问题分析

摘要

According to the aviation aluminum alloy structure with different parts, the research status and progress were an-alyzed systematically from three aspects: corrosion mechanism, corrosion behavior and corrosion prediction technology. On this basis, the paper made clear further problems need to be further studied on the corrosion prediction technology for the aluminum alloy of airplane: determination of surface corrosion environment for aircraft structure, accurate measurement of electrochemical properties on material corrosion in Marine atmosphere environment and selection of corrosion prediction model.%针对不同的航空铝合金结构及部位,从腐蚀机理、腐蚀行为和腐蚀预测技术三方面较为系统地分析了研究现状及进展.在此基础上,明确了航空铝合金腐蚀预测技术需要进一步研究的问题,分别为飞机结构表面腐蚀环境的确定问题,材料在海洋大气环境下腐蚀电化学性能的准确测量问题,腐蚀预测模型的选取问题.
