Hard Chrome Build Up up to .020” tk

A heavy dense deposit of chrome and chrome build up is used to provide wear resistance on such parts as pistons, cylinders, aircraft engine parts, cutting tools, dies, oil tools, and valves. Hard chrome is put directly onto the substrate, not on top of nickel plating, and is put there as a very heavy coating essentially for wear and friction reduction.

Some typical deposits may be used as follows:

• 7.5 microns (0.0003") to 25 microns (0.001") Flash coatings to engraved rollers, embossed cylinders and coatings to other rollers and shafts that are not subject to too much abrasion, and for slight corrosion protection.

• 25 microns (0.001") to 76 microns (0.003") Thicker flash coatings for better abrasion properties, and for slightly better corrosion protection.

• Over 76 microns (0.003") Heavy deposits which usually require grinding and or polishing after plating. Used when a good surface finish is required, for such uses as plastic and film manufacture, calendar rollers in paper and board production.
