【摘要】通过极化曲线,电化学阻抗谱,恒流放电曲线等方法研究了AZ31镁合金在1.16,1.74,2.30,2.90和3.50mol/L的Mg(ClO4)2溶液中的腐蚀行为和电化学性能以及放电行为。结果表明,AZ31镁合金在2.90mol/LMg(ClO4)2溶液中腐蚀电流密度最大,传递电阻最小,放电容量最大。AZ31镁合金在Mg(ClO4)2溶液放电过程中会生成致密腐蚀产物,阻塞放电。并对镁一次电池的发展方向进行了展望。更多还原

【Abstract】 Corrosion behavior, electrochemical characters and discharge performance of AZ31 magnesium alloy in various Mg(ClO4)2solutions were investigated by means of polarization curve,electrochemical impedance spectroscopy and constant current discharge. The result shows that in2.90 mol/L Mg(ClO4)2 solution, the transfer resistance of the alloy is the smallest and thereby the discharge capacity is the highest. The dense layer of corrosion products formed during the discharge process in Mg(ClO4)2solution, which could inhibit the discharge process by covering effect.Finally, this paper prospects the development direction of magnesium primary batteries.更多还原
