中文摘要：

AP65 Mg 合金的腐蚀行为上的铟增加的效果被检验。修改 AP65 展出的铟加速了 pitting 腐蚀和全面腐蚀，但是有几乎在腐蚀的发作的没有潜伏期。极化曲线大小显示铟修改了 AP65 有更否定的腐蚀潜力，它是电气化学的激活的一个改进方面。从 0.126 ～ 0.868 妈 / 厘米的腐蚀水流密度增加 < 啜 class= “ a-plus-plus ” > 有或没有 2.0% 的 2 ( 集体部分) 铟增加。AP65 的吝啬的潜力否定地由增加 2.0% 铟从 1.491 V 变到 1.584 V。AP65 的腐蚀表演上的铟增加的效果似乎与合金的 cathode-to-anode 区域比率的减少被联系，它可以改变电气化学的阳极和合金的阴极极化行为。

英文摘要：

The effect of indium addition on the corrosion behavior of AP65 Mg alloy was examined. The indium modified AP65 exhibits accelerated pitting corrosion and overall corrosion, but there is almost no incubation period at the onset of corrosion. Polarization curve measurements indicate that the indium modified AP65 has more negative corrosion potential, which is an improvement aspect of the electrochemical activation. The corrosion current density increases from 0.126 to 0.868 mA/cm2 with and without 2.0% （mass fraction） indium addition. The mean potentials of AP65 negatively shift from -1.491 V to -1.584 V by adding 2.0% indium. The effect of indium addition on the corrosion performance of AP65 seems to be associated with the decrease of cathode-to-anode area ratio of the alloy, which may change the electrochemical anode and cathode polarization behavior of the alloy.
