摘　　要：采用浸涂工艺,用W-78和A-1200硅烷偶联剂对金属镁进行表面处理,然后固封制备成镁电极。对比分析了有和无硅烷偶联剂处理的镁电极的电化学行为。研究表明,两种硅烷偶联剂都可以改善镁电极的性能,显著提高了测试结果的重现性,其中A-1200效果更好。讨论了硅烷偶联剂W-78和A-1200的作用机理。The surface of magnesium was pretreated in the W-78 or A-1200 silane solution by dip-coating process as a base coating, then the magnesium electrodes with silane coupling agents were followed, of which the electrochemical properties and others are compared with the one that without silane coupling agents. The two silane coupling agents could improve the performance of the magnesium electrode, which make the results of electrochemical test recur better, A-1200 is more superior to W-78. The affecting mechanism of W-78 and A-1200 silane solution is summarized in this paper.
