Standard Specification for Electrodeposited Engineering Chromium Coatings on Ferrous Substrates
1.1 This specification covers the requirements for electrodeposited chromium coatings applied to ferrous alloys for engineering applications.
1.2 Electrodeposited engineering chromium, which is sometimes called "functional" or "hard" chromium, is usually applied directly to the basis metal and is much thicker than decorative chromium. Engineering chromium is used for the following:
1.2.1 To increase wear and abrasion resistance,
1.2.2 To increase fretting resistance,
1.2.3 To reduce static and kinetic friction,
1.2.4 To reduce galling or seizing, or both, for various metal combinations,
1.2.5 To increase corrosion resistance, and
1.2.6 To build up undersize or worn parts.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
