Electrochemical behaviour of LY12CZ under applied stress

  • 摘要: 利用动电位极化和电化学阻抗谱技术对应力加载下的LY12CZ铝合金在3%NaCl水溶液中的腐蚀行为进行了研究,考察了应力作用对LY12CZ在3%NaCl水溶液中的阳极极化行为、自腐蚀电位和破裂电位以及极化电阻和双电层电容大小的影响.结果表明,在加载应力时LY12CZ的阳极极化曲线和自腐蚀电位、破裂电位均明显负移;在浸泡时间相同的情况下,极化电阻也随应力的增加而显著降低,在应变强化阶段力学化学效应达到最大.破裂电位的负移和极化电阻的降低说明应力对LY12CZ的局部腐蚀有明显的影响.
