Abstract The effect of stress on the polarization curve of high pressure die cast aluminum alloy in sodium chloride solution was evaluated by mechano-electrochemical experiments and boundary element electrostatics simulations. The polarization curve was measured under a constant stress condition, and a decrease in natural potential due to stress was observed. A periodic arrangement of intact and damage surfaces was assumed in the mechanically damaged oxide film, and the polarization curve of the damage surface was identified. The simulation results showed that the decrease in natural potential is explained by the nucleation of the damage surface by plastic strain.

应力对铸铝合金在氯化钠溶液中极化曲线影响的实验及边界元法研究

摘要 通过机械电化学实验和边界元静电模拟，研究了应力对高压压铸铝合金在氯化钠溶液中极化曲线的影响。在恒定应力条件下测量极化曲线，观察到由于应力导致的自然电位降低。在机械损伤的氧化膜中假设完整和损伤表面的周期性排列，并识别损伤表面的极化曲线。模拟结果表明，自然电位的降低是由塑性应变引起的损伤表面形核解释的。
