摘要:

结合民机结构使用特点,参考国内外已有研究成果,提出了适用于民机结构外露腐蚀关键部位的涂层加速环境谱。该谱由温湿暴露、紫外照射、低温疲劳和盐雾4个环境块构成。给出了各环境块参数的确定方法及加速谱与外场实际使用环境的当量加速关系。通过民机机翼下翼面典型模拟试件加速腐蚀若干周期的试验,验证了该加速谱和当量加速关系的合理性。该谱的提出为腐蚀条件下民机结构日历寿命评定提供了重要的依据。

Abstract:

An accelerated corrosion environment spectrum of surface coating of outside corrosion critical area of civil aircraft structure is presented, combined with the characteristics of the use of civil aircraft and referred to existing research results. The spectrum is composed of hothumid environment, ultraviolet radiation, low temperature fatigue and salt spray. The method of determination the parameters of every process and the equivalent relation between the accelerated spectrum and the actual use environment are presented.
