| 摘 要： | 用电化学方法研究了Mg-15Li合金在碱性NaCl溶液中的腐蚀行为.结果表明：在强碱性pH=13及扫描电镜环境下，当Cl-浓度低于0.4 mol/L时，合金表面形成稳定的钝化膜；随Cl-浓度增加，点蚀电位逐渐降低.

| Abstract: | The corrosion behavior of a Mg-15Li alloy in alkaline solution of NaCl was investigated by means of electrochemical means,and the corroded surface was examined by using SEM.The result showed that a stable film was formed on the alloy surface under the condition of pH=13 and concentration of Cl- less than 0.1 mol/L;the pitting corrosion potential gradually decreased with the increase of Cl- concentration. |
