The invention relates to an in-situ anti-corrosion process for aircraft aluminum alloy component cracks after cold spraying reinforcement repair. The in-situ anti-corrosion process comprises the following specific steps of performing polishing pretreatment on the in-situ surface of an aluminum alloy component after cold spraying reinforcement repair; preparing an allobutane oxidation solution by matching 0.75 g of allobutane 1200S with every 100ml of deionized water; brushing the in-situ surface of the aluminum alloy component subjected to cold spraying, reinforcing and repairing by using theprepared allobutane oxidation liquid until the in-situ surface is golden yellow; and applying s060215 organic anticorrosive paint on the in-situ surface of the aluminum alloy component for secondary protection after cold spraying reinforcement repair is conducted on the aluminum alloy component. Compared with the prior art, the surface of the 7075 aluminum alloy coating is prepared through cold spraying after treatment of the allobutane oxidation liquid, and S060215 organic anticorrosive paint is brushed for secondary protection, so that the anticorrosive effect is remarkably improved, and thecorrosion resistance of the aluminum alloy coating is greatly improved; and the aircraft aluminum alloy component does not need to be disassembled from the aircraft, so that the repair difficulty andthe repair labor intensity are reduced, and the repair cost is saved.

    本发明涉及一种飞机铝合金构件裂纹冷喷涂补强修理后原位防腐工艺,具体步骤如下:对铝合金构件冷喷涂补强修理后原位表面进行打磨预处理;用每100ml去离子水配0.75g阿洛丁1200S的配比进行配制阿洛丁氧化液;用配制好的阿洛丁氧化液对铝合金构件冷喷涂补强修理后原位表面进行涂刷至金黄色;在铝合金构件冷喷涂补强修理后原位表面涂刷S06‑0215有机防腐涂料进行二次防护。与现有技术相比,本发明通过采用阿洛丁氧化液处理后的冷喷涂制备7075铝合金涂层表面,以及涂刷S06‑0215有机防腐涂料进行二次防护,使得防腐蚀效果得到显著提升,大幅度提高了铝合金涂层的耐腐蚀性能;且无需将飞机铝合金构件从飞机上拆卸,降低了修理难度以及修理劳动强度,节省了修理成本。
