Abstract The effect of coating used to cover airplane on corrosion fatigue behaviour of LY12CZ aluminum alloy has been studied.The corrosion fatigue lives for uncoated and coated specimens in both air and 3.5% NaCl solution were compared,and the evolution of free corrosion potential with cyclic number was measured.The equations of fatigue and corrosion fatigue lives were obtained on some experiment conditions by quantitative analysis.The results showed that the corrosion fatigue life of LY12CZ aluminum alloy was greatly improved by coating.

Key words: coating of covering airplane LY12CZ aluminum alloy corrosion fatigue life
