ANALYSIS OF TRANSIENT CURRENT FOR LY12CZ ALUMINUM ALLOY IN NaCl SOLUTION DURING CORROSION FATIGUE
LY12CZ铝合金在NaCl溶液中腐蚀疲劳应变电流的分析

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.
