Abstract

A bearing element having an adherent score-resistant coating on its surface comprising a carbonized layer of an organic resin in which the layer is carbonized by ion implantation. The ion implantation is controlled to not only provide graphite-like and diamond-like structures in the carbonized coating but to also produce chemical bonding between carbon atoms of the resultant coating and atoms of the bearing surface.
