| Abstract: | Accelerated corrosion test of LY12CZ aluminum alloy was carried out in EXCO solution and the corrosion depth of the alloy was measured.Further more corrosion damage of aircraft LY12CZ structure with different service periods in true airport environment was counted.Based on the corrosion damage data of the two different environments and the corrosion damage equivalent relation,the equivalent relation factor between the EXCO solution and true airport environment was found.Then the neural network model based o... |
