    Abstract: 本研究主要探討鎂及鎂合金金屬於水溶液環境中的電化學腐蝕行為,並且從文獻中所得極化行為之實驗結果,利用Butler-Volmer方程式及Tafel方程式模擬出本研究之適當反應機制及其極化曲線。
    而從模擬結果發現,在低電位區域鎂金屬的電化學氧化產生一價鎂離子Mg+,且清楚的發現在高電位部分區域有鎂金屬的陽極氧化部分有二價鎂離子Mg2+的析出,此外,可發現在中間電位部分區域存在高低兩電位區之結果依一定比例組成模擬出本次研究結果。
    This study focused on the electrochemical corrosion behavior of magnesium and magnesium alloy metal in an aqueous environment. Using Butler-Volmer equation and the Tafel equation to simulate the polarization curve of this study. As we found that the unipositive is involved as an early step in the electrochemical oxidation of magnesium at low potential region. And it is clear that, during the anodic oxidation of magnesium metal, the transfer simultaneously of two electrons to form at high potential. Besides ,there is a proportion combine two curves to involve the consequence at middle potential.
