A hydrogenated diamond-like coating ('H-DLC') for metallic substrates provides improved reliability. The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be used between the metallic substrate and the H-DLC. H-DLC coatings can, for example, be used in bearings and gears to reduce the occurrence of micropits and, ultimately, product failure.

Pitting resistant carbon coatings

A method for making a pitting resistant carbon coating that includes a hydrogenated diamond-like coating ('H-DLC'). The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be deposited on a metallic substrate and the deposited H-DLC on the bonding layer.
