    摘要:

    制備了Mg-14Li-1Al (LA141), LA141-0.3Y, LA141-0.3Sr和LA141-0.3Y-0.3Sr合金，采用動電勢極化曲線，恒電勢電流-時間曲線，交流阻抗技術(shù)以及掃描電子顯微鏡等手段測試了這些合金在0.7 mol/L氯化鈉溶液中的電化學(xué)性能。研究了氧化鎵作為電解液添加劑對鎂合金恒電勢放電性能的影響。結(jié)果表明：在有與無氧化鎵的情況下，合金的電化學(xué)活性和利用效率都按照以下順序遞增：LA141< LA141-0.3SrLA14-0.3Sr>LA141-0.3Y>LA141-0.3Y-0.3Sr。掃描電子顯微鏡觀察發(fā)現(xiàn)，鎂中添加Y和Sr可以阻止合金表面濃密氧化物的生成并且可以加快其在電解液中的脫落。在提高鎂合金電化學(xué)性能方面，Y的作用比Sr的作用強，當Y和Sr同時添加進鎂合金中，效果都將比單獨添加Y和Sr的任何一種更好。LA141-0.3Y-0.3Sr表現(xiàn)出了最好的電化學(xué)活性和利用效率，而且合金表面的放電產(chǎn)物也最疏松。

    Abstract:

    Mg-14Li-1Al (LA141), LA141-0.3Y, LA141-0.3Sr and LA141-0.3Y-0.3Sr alloys were prepared and their electrochemical behavior in 0.7 mol/L NaCl solutions was investigated by means of potentiodynamic polarization, potentiostatic current-time and electrochemical impedance spectroscopy measurements as well as by scanning electron microscope examination. The effects of gallium oxide as an electrolyte additive on the potentiostatic discharge performances of these magnesium alloys were studied. The discharge activities and utilization efficiencies of these alloys increase in the order: LA141LA141-0.3Sr>LA141-0.3Y>LA141-0.3Y-0.3Sr. Scanning electron microscopy indicates that the alloy elements Y and Sr can prevent the formation of dense oxide film on the alloy surface and accelerate the peeling off the oxide products. In the respect of improving the electrochemical performance Y is more obvious than Sr and it is the most significant when Y and Sr are alloyed in magnesium at the same time. LA141-0.3Y-0.3Sr exhibits the best performance in terms of activity and utilization efficiency and the most loose oxide products on alloy surface.
