摘要
通过对两种缺口件进行人工加速气候环境试验,对比两种缺口件的3类涂层体系的质量、失光率和表面绝缘电阻随老化周期的变化规律,优选出适宜飞机典型结构件的涂层A,并拟合了该缺口件DFR值与加速老化周期的线性关系,建立了3类涂层体系的失光率与加速老化周期之间的定量关系,研究了加速气候环境试验对缺口件涂层表观形貌的影响,分析了缺口件涂层体系的老化特点。
The artificial accelerated aging test of two kinds of notched specimens is carried out.The change laws of the quality,the gloss reduction rate and the surface insulation resistance of three kinds of coating of the two kinds of notched specimens with the aging cycle are contrasted,and the coating A which is suitable for the typical structural parts of aircraft is optimized. The linear relationship of the notched DFR value with the accelerated aging cycle is simulated,and the quantitative relationship of gloss reduction rate of the three kinds of coating system with accelerated aging cycle is built. The effects of the accelerated climate environmental test on the coating surface morphology of notched specimens are studied,and the aging characteristics of the notched coating system are analyzed.
