Title
(EN) PLASMA TREATMENT OF CARBON-BASED MATERIALS AND COATINGS FOR IMPROVED FRICTION AND WEAR PROPERTIES
(FR) TRAITEMENT PAR PLASMA DE MATÉRIAUX À BASE DE CARBONE ET REVÊTEMENTS POUR AMÉLIORER LES PROPRIÉTÉS DE FROTTEMENT ET D'USURE
Abstract
(EN)
A method of plasma modification of a film includes applying about -400 V to about -600 V to a gas in a chamber to generate a gas-discharge plasma; and subjecting the film to the gas-discharge plasma to form a plasma-modified film, where the gas comprises H2, H2S, NH3, deuterium, methane, or a mixture of any two or more. Films may be prepared. Devices coated with the films may be prepared.
(FR)
L'invention concerne un procédé de modification de film par plasma comprenant l'application d'environ -400 V à environ -600 V à un gaz se trouvant dans une chambre pour générer un plasma à décharge gazeuse; et le traitement du film avec le plasma à décharge gazeuse pour former un film modifié par plasma, le gaz comprenant du H2, du H2S, du NH3, du deutérium, du méthane ou un mélange de deux ou plus de deux de ces gaz. Il est ainsi possible de préparer des films et des dispositifs recouverts avec les films.
