| Objective To research repairing techniques for surface protecting system of aircraft aluminum connection part. Methods According to the corrosion damage features of the aircraft aluminum connection structure, the original protecting system type, the service environmental features and so on, the repairing material and the repairing process were selected and five different repairing methods (RM) for the protecting system were developed. By carrying out the accelerated corrosion test under the environment spectrum of the typical aircraft coating accelerated test, the preferred repairing method adapted for the surface protecting system of the aircraft aluminum connection structure was selected. Results At 2 cycles of the accelerated test, the surface of the repairing part began shedding by using RM4. At 6 cycles of the accelerated test in the fastening area, the repairing part by RM1, RM, RM3 or RM5 were all excellent or good in the indicators of color, chalking, cracking, blistering and peeling, however, only the repairing part by RM3 was good in the indicator of rusting. In the non-fastening area, the repairing part by RM1, RM2, RM3 or RM5 were all excellent or good in all indicators. Conclusion RM3 was more suitable for repairing of the surface protecting system of the aircraft aluminum connection part. |
