摘要
采用电刷镀设备对飞机硬铝合金蒙皮表面局部的腐蚀进行阳极化,然后实施喷漆,从而达到了原位快速修复的目的。介绍了快速修复的原理及工艺过程。采用间隙盐雾试验考察了修复层的耐蚀性能。结果表明,飞机铝合金蒙皮修复后耐蚀性能为处理前的4倍,使用寿命得以延长。
The local corrosion area on the hard aluminum alloy of aircraft skin surface was rapidly renovated in-situ by anodising with brush electroplating equipment firstly and then spray painting. The principle and process of rapid renovation were introduced. The corrosion resistance of renovated film was measured by batch salt spray test. The results show that the renovated aircraft aluminum alloy skin has 4 times of corrosion resistance and longer life-span than that before renovation.
