1.1This specification covers the requirements for electrodeposited chromium coatings applied to ferrous alloys for engineering applications.

1.2Electrodeposited 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:

1.2.1To increase wear and abrasion resistance,

1.2.2To increase fretting resistance,

1.2.3To reduce static and kinetic friction,

1.2.4To reduce galling or seizing, or both, for various metal combinations,

1.2.5To increase corrosion resistance, and

1.2.6To build up undersize or worn parts.

1.3This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
