摘要
A detailed study of the production opportunities for composition modulated alloy electrodeposits by pulsed current techniques with Zinc-Iron alloys is reported. II is shown that by using a chloride solution, with the additional capability of variable agitation rates, a full range of alloy compositions is possible with nanometre layering attainable using single or double bath methods. Furthermore; by the use of a high concentration of ammonium chloride ostensibly as 'conductivity' salt, the mechanism of deposition may be modified through control of a thin cathode oxide/hydroxide film.
