Objective To study the validity of the YTF-3 aircraft corrosion inhibitor with hard film applied in the aircraft maintenance/repair. Methods Referring to the requirements and measuring methods from the new American military specification of MIL-DTL-85054D（AS） and the Boeing company standard of BMS 3-35, both the physical-chemical properties and the performing characters of the YTF-3 aircraft corrosion inhibitor with hard film developed by ourselves were evaluated. Results The flash point of the YTF-3 aircraft corrosion inhibitor was above38 ℃, and the inhibitor was safe to use, transfer and store. The basic performing characters of the corrosion inhibitor were good. It was rapid to dry and convenient to use or remove. The corrosion inhibitor effectively inhibited corrosion of metal materials, and would not cause corrosion of aircraft metals. It had excellent properties of functional penetration and synthetic sea water displacement, so it can be applied to the sandwich structures in the airplane to leave a protective film. Meanwhile, its resistances to different kinds of corrosion were satisfactory. What′s more, as the YTF-3 aircraft corrosion inhibitor had advantages of high and low temperature resistances as well as ultraviolet ray resistance, it can be used on internal and external parts of the aircraft. Conclusion The YTF-3 aircraft corrosion inhibitor with hard film satisfies the requirements of prevention of aircraft corrosion, and can be applied in the aircraft maintenance/repair.
