摘要
研究了 LC4铝合金在 3 .5% Nacl水溶液中 ,应力腐蚀裂纹尖端区域与内部其它各样块之间 ,裂纹尖端区域与外自由表面之间电流随时间的变化 .结果表明 :活化与钝化是 LC4铝合金应力腐蚀裂纹尖端的电化学特征 ,裂纹尖端反应速度主要取决于裂纹尖端自身微电池的作用 .
This paper introduces the variation of current with time for LC4 Aluminum alloy samples between insides of the stress corrosive cracking and outside of free surface in 3.5% NaCl solution. The results have shown activating and passivating is the electrochemical characteristics of the stress corrosive crack tip on LC4 aluminum alloy and the reaction rate of the crack tip primarily depens upon the effect of the microcell on the crack tip itself.
