Article Preview

The important factors induced corrosion damage of aircraft are analyzed. Based on airport ground environment spectrum, the LY12CZ specimens are tested in laboratory using the accelerated corrosion spectrum. Some specimens are exposed on deck in tropical marine environment. The corrosion characteristic of the coating and base material is inspected and corrosion damage size is measured after the specimens have been accelerated corrosion tested for 5,10,15,20 and 30 years respectively and the specimens have been exposed on deck. The corrosion characteristic of specimens are analyzed and compared using several evaluating indicator. The results show that the corrosion damage characteristic of the specimen in the test is consistent with which in service situations. And the corrosion of material exposed in ocean environment is obviously accelerated. The corrosion depth is measured and the mass loss by corrosion is weighed. The distribution function of the corrosion depth and the characteristic of the mass loss by corrosion are given. The corrosion equivalent relationship under these two environments is determined by contrasting the corrosion depth and the corrosion characteristic.
