Chromium plating, in a decorative nickel-chrome system, provides a tarnish-resistant, pleasing bluish, brilliant and clear deposit on the Nickel surface. The deposit is hard and therefore, resistant to abrasion and wear. Thus, a very thin coating of 0.25 to 0.8 microns of chrome provides a durable and attractive finish.
Thick hard chrome deposits are useful where good surface hardness, abrasion, wear resistance and anti-seize properties are desired. Hard Chromium is extensively used for gauges, cutting tools, metal forming, dies, machine parts such as piston rings, cylinder liners, crankshafts for marine and aero engines, bearings hydraulic gears, salvage of worn and defective machinery parts, moulds and printing rollers.
