BEARING WHICH HAS A SURFACE FORMED BY THE CONVERSION OF A CARBON METAL CARBIDE IN THE METAL CARBIDE SURFACE THROUGH HALOGEN ATTACK.

摘要

Bearing arranged as part of a mechanical device, said mechanical device including a solid part in friction contact with said bearing, so that there is a relative movement between said solid part and said bearing when the mechanical device is operated, in which the bearing It is formed from a metal carbide that is depleted metalically on the bearing surface to provide a carbon surface layer, the carbon surface layer comprising an internal carbon sublayer having a Raman peak intensity ratio of 1D / 1G of 0 , 8 to 1, 20, and a more graffiti external carbon sublayer.
