| Abstract: |
| This paper aims to evaluate the anti-corrosion ability of a new type of aircraft protective cover. Firstly, the corrosion inhibition ability of vapor phase was tested. Secondly, according to the accelerated environmental test spectrum, the aluminum alloy specimens wrapped by the new aircraft protective cover and waterproof canvas were subjected to salt spray test and UV test. Finally, the immersion test of the new aircraft protective cover and waterproof canvas was carried out. The gasification anticorrosion film layer of the new aircraft protective cover has better corrosion inhibition effect. In the salt spray test, the corrosion degree of the specimen covered by new aircraft protective cover, waterproof canvas and no package increased successively. In the UV test, the color difference value of the specimen covered by waterproof canvas was gradually larger than that of the specimen covered by new aircraft protective cover with the growth of cycle, but all of them was less than that of the unwrapped specimen. In the immersion test, the pH value of the solution of the new aircraft protective cover, waterproof canvas and original soaking decreased gradually. The result shows that the new aircraft protective cover has better corrosion inhibition ability of vapor phase, and is superior to the waterproof canvas in corrosion inhibition ability, ultraviolet protection ability and resistance to acid solution. |
