飞机典型结构件防护涂层耐腐蚀试验对比研究

Comparative Research on Protection Coating CorrosionResistant Test of Aircraft Typical Structure

摘要:

基于2种涂层的飞机典型结构模拟试验件加速腐蚀及老化试验,得到涂层光泽度和色差随加速腐蚀时间的变化规律。利用灰色关联分析方法,对影响涂层腐蚀损伤的9个评定指标进行量化比较,计算出2种涂层防护体系评价指标与参考标准之间的关联度大小,并对2种涂层防护体系进行了综合评定。结果表明,2种涂层光泽度和色差变化均随加速腐蚀时间增加而增大,TB06-9涂层较H06-076涂层变化更明显,H06-076涂层的防护效果优于TB06-9涂层。

Abstract:

Based on accelerated corrosion and ageing test for typical structure with two coatings of aircraft, the change law of gloss and chromatic aberration for coating along with the accelerated corrosion time was obtained. Using the grey relational analysis method to compare nine evaluating indexes that influence coating corrosion damage quantitatively, the relational degree between two coating protecting systems and reference standard were figured out, a comprehensive evaluation for the two coating protected systems was obtained. The result indicated that the variation of gloss and chromatic aberration for two coatings increased along with the accelerated corrosion time, the change of TB06-9 coating was more obvious than H06-076 coating, so the H06-076 coating was better than the TB06-9 coating.
