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.

1. A bearing element having and adherent, hard, antifriction coating thereon, wherein the bearing element has a surface consisting essentially of an iron-based alloy for sliding contact with metals, such as aluminum based alloys, a carbonized layer thereon of a sulfur-free methacrylate-type resin that contains silicon carbide, graphic-like and diamond-like crystalline microstructures therein, and an interfacial zone between the carbonized coating and the iron-based alloy surface containing chemical compounds of iron and carbon that bond the carbonized coating to the iron-based alloy surface.
