摘要:

利用CorrosionMaster软件对航空发动机压气机部位典型连接结构在酸性盐雾和湿热环境的腐蚀情况进行仿真，并依据国军标开展典型连接件的酸性盐雾试验和湿热试验，最后将仿真结果与试验结果进行验证。结果表明：利用CorrosionMaster软件仿真得到的压气机典型连接件酸性盐雾环境和湿热环境下的腐蚀结果与试验结果相一致，仿真结果对于预测评估金属结构的腐蚀风险具有参考价值。

Abstract：

Corrosion behavior of typical connected parts for aeroengines compressor in acid salt spray and humid-heat environment were simulated with CorrosionMaster software, meanwhile, of which the tests by acid salt spray and in humid-heat conditions were carried out according to the national military standards of China (GJB). Finally, the simulation results were verified with the real test results. It follows that the simulation generated corrosion data of the typical connected parts by acid salt spray and in humid-heat environment are consistent with those acquired by the real tests, therefore, the simulation results can provide valuable reference for corrosion risk prediction and evaluation of metal structures.

Key words： corrosion simulation aeroengine CorrosionMaster software salt spray humid
