Abstract:Effects of MnCl 2 and temperature on the electroplating of Al Mn alloys are very significant. At lower concentrations of MnCl 2, solid solution of Mn in Al and amorphous Al Mn phases can be deposited, while at higher concentrations of MnCl 2 and lower temperatures, only a single amorphous Al Mn phase can be formed in the stationary melt. The electrodeposition of Al Mn alloys with amorphous Al Mn phase is characterized by very small nucleus number density and 2 dimensional growth, leading to high quality electroplates with few defects.
