Abstract (en)
[origin: WO9958741A1] This invention is directed to plating using a coating bath that provides a hard, wear and corrosion resistant, ductile coating on a substrate, said bath having a pH of about 10 to about 14 and comprising: (1) about 0.175 to about 2.10 moles per gallon of coating bath of nickel ions; (2) an effective amount of lead tungstate to stabilize the bath and to form a continuous coating free from blotches without any substantial deposition of lead tungstate in the coating; (3) an effective amount of metal ion complexing agent in an amount sufficient to inhibit precipitation of said metal ions from the coating bath; and (4) an effective amount of a borohydride reducing agent.
