摘要
A process and aqueous composition for electrodepositing a uniform, adherent substantially black nickel deposit on a conductive substrate. The aqueous solution is of a pH ranging from about 8 to about 12 and contains nickel ions in combination with a controlled effective amount of a selected class of bath soluble amines to attain the black nickel deposit. The aqueous solution may further optionally contain supplemental darkening enhancing agents, conductivity salts and wetting agents of the types conventionally employed in nickel electroplating solutions.
