摘　　要：针对传统航空零件表面处理过程中孔保护材料和方法的保护效果不佳的问题,通过使用由耐高温、耐强酸及耐强碱材料制成的T型硅橡胶塞、柱型硅橡胶塞、机械膨胀塞,以及刷涂可剥离保护胶,在表面处理过程中对各类孔进行保护,通过目视检查和装配验证评价了各自的保护效果。结果表明,上述4种方法对各类孔都有很好的保护效果。Aiming at the poor protection for the holes on aerospace parts during surface treatment when using the traditional protection materials and methods, the application of several kinds of plugs made of the materials resistant to high temperature, strong acid, and strong alkali(i.e. T-type silicone rubber plug, columnar silicone rubber plug, and mechanical expansion plug) and the brushing of a strippable sealant for protection of different holes during surface treatment was tested and evaluated by visual inspection and assembly verification. The results showed all of the four methods have good protection effectiveness for different kinds of holes.
