ORGANIC SULFIDES USEFUL FOR THE ELECTRODEPOSITION OF BRIGHT NICKEL IRON DEPOSITS

摘要

An aqueous bath suitable for the electrodeposition of a bright iron nickel electrodeposit onto a substrate susceptible to corrosion comprising iron ions, nickel ions, a bath soluble complexing agent containing at least two complexing groups, said groups independently selected from the group consisting of carboxy and hydroxy, providing at least one group is a carboxy group; the bath having a pH from 2.5 to about 5.5 and containing a sulfide.
