摘　　要：目的对一种新型飞机防护罩的防腐蚀性能进行评价。方法首先,对新型飞机防护罩进行气相缓蚀能力检测;其次,根据加速环境试验谱,将被新型飞机防护罩与防水帆布包裹的铝合金试件进行盐雾试验和紫外试验;最后,将新型飞机防护罩与防水帆布进行浸泡试验。结果新型飞机防护罩的气化性防锈膜层缓蚀效果较好。在盐雾试验中,试件的腐蚀程度顺序为被新型飞机防护罩包裹试件<被防水帆布包裹试件<未包裹试件。在紫外试验中,随着周期增长,被防水帆布包裹试件的色差值逐渐比被新型飞机防护罩包裹试件的色差值大,但均小于未包裹试件的色差值。在浸泡试验中,浸泡溶液p H值的大小为新型飞机防护罩>防水帆布>原浸泡溶液。结论该新型飞机防护罩有较好的气相缓蚀能力,且缓蚀性能和防紫外线能力及对酸性溶液的抵抗力上均优于防水帆布。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.
