摘　　要：在普通钢板上熔盐电积沉Al Mn非晶态合金 ,熔盐组成为 :AlCl3:KCl :NaCl=2 :0 .5 :0 .5 (摩尔比 )。讨论了阴极电流密度、电镀温度等参数对铝锰非晶合金沉积速度的影响 ;当阴极电流密度达到 42mA cm2 时 ,沉积速度达到1.4g m2 .min ,之后则成反比关系 ;当温度达到 490K时 ,电镀时间为 12min ,沉积速度达到 1.4g m2 .min ,之后沉积速度趋于平稳并略有降低。Adding MnCl 2 in AlCl 3 KCl NaCl molten salts the Al Mn amorphous coating layer is obtained on the steel board.The suitable bath composition for the formation of Al Mn amorphous alloys are as follow: AlCl 3:KCl:NaCl=2:0.5:0.5(mol).The effects of negative current density, temperature ect.on electrodeposition velocity of Al-Mn coating layers are studied. The results show that when the negative current desity is 42mA/cm 2, the velocity is 1.2g/m 2.min,then the velocity is inverse ratio to the current desity, then temperature is 490K and the time is 12 min, the velocity is at 1.4g/m 2.min,then the velocity tends to mild and decreases lightly.
