ENVIRONMENTALLY FRIENDLY NICKEL ELECTROPLATING COMPOSITIONS AND METHODS

摘要

Environmentally friendly nickel electroplating compositions enable the electroplating of nickel deposits which are bright and uniform and inhibit corrosion of gold layers deposited on the bright and uniform nickel deposits. The environmentally friendly nickel electroplating compositions can be used to electroplate bright and uniform nickel deposits on various substrates over a wide current density range. The composition comprises one or more N-benzylpyridinium sulfonate compounds.
