| Objective To put forward a set of engineering available In-situ surface treatment methods for bonding-repair of aircraft structure. Methods A portable phosphoric acid anodizing device was used to study in-situ surface treatment on typical aluminum alloy substrates, along with comparative study involving micro morphology analysis, energy spectrum analysis and durability test. Results The film created by in-situ phosphoric acid anodized on aluminum alloy substrates showed a thick honeycomb structure, and was rich in oxygen, which were the signs of corrosion resistance and durability capacity. Conclusions The in-situ surface treatment method for bonding-repair of aluminum alloy structure could improve the durability of bonding-repair structure in harsh environments, and the durability was equal to that of the traditional Tank PAA. |
