Nickel Plating

Widely used as an under­coat for chromium plating. Small amounts of complex organic addition agents are in­cluded in the nickel sulfate plating solu­tions to provide a bright coat. Steel articles are sometimes thinly copper plated before application of nickel and chromium. By selecting suitable addition agents, scratches can be leveled out and eliminated as the deposit builds up. See Chromium Plating.
