研究了LY12CZ铝合金在 3.5 %NaCl溶液中不同恒电位下腐蚀疲劳 (CF)应变电流行为 .结果表明应变电流波形与铝合金表面的钝化膜有较大关系 ,钝化速率和加载频率是其中两个重要的影响因素 .
The transient current behavior during corrosion fatigue was studied for an LY12CZ aluminum alloy in 3.5 % NaCl solution under load control at different imposed constant potential. The results showed that the passivation film played an important role in the behavior of transient current response during corrosion fatigue. The loading frequency and passivation rate were the most important factors to affect the transient current.
