摘要:
The present invention relates to the electrodeposition of zinc nickel alloy on a variety of electrically conducting substrates in a medium which seeks to provide improved deposit distribution and operable current density range. This is achieved through a bath comprising zinc ions, nickel metal ions, and a suitable combination of one or more urea based polymers and non-polymeric complexing agents capable of holding nickel metal ions in alkaline solution and an electrolytic process whereby the bath is used to electrodeposit zinc nickel alloy on electrically conducting substrates.
