Nanocrystalline CoP coatings prepared by different electrodeposition techniques

摘要

A Watts-type cobalt bath containing additives has been used to prepare magnetic nanocrystalline CoP alloys. Coatings several microns thick were obtained using galvanostatic pulse plating (PP) and direct current (DC) electrodeposition. In both cases, compact deposits with slightly different grain sizes were achieved. The CoP deposits were magnetically softer than amorphous P-richer CoP electrodeposits and also than crystalline Co and Co-alloys prepared previously by electrodeposition.
