The present invention is a non-metallic article that has been coated with a diamond-like carbon (DLC) coating. A coated article of the present invention has increased hardness, increased abrasion resistance, and a reduced coefficient of friction when compared with the same properties of the article prior to the article being coated. DLC coatings of the present invention are applied in a chamber filled with hydrocarbon plasma and with application of electrical pulses.
La présente invention concerne un article non métallique qui a été revêtu d'un revêtement en carbone sous forme de diamant amorphe (DLC). Un article revêtu selon cette invention présente une dureté améliorée, une résistance à l'abrasion améliorée et un coefficient de frottement réduit, par comparaison avec les mêmes propriétés dudit article avant son revêtement. Les revêtements en DLC selon cette invention sont appliqués dans une chambre remplie de plasma d'hydrocarbure et par application d'impulsions électriques.
