摘要: 对核电用奥氏体不锈钢进行固溶和敏化处理,对部分固溶试样进行Fe+和He+辐照,随后测量了4种处理状态试样的再活化率(EPR),并观察表面形 貌.结果表明:经He+辐照试样出现了2.88%的再活化率,敏化试样的再活化率是19.5%,固溶试样和经Fe+辐照试样的再活化率为0.离子辐照试样的表面形貌与固溶或敏化试样完全不同.

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.
