Title
(EN) DIAMOND-LIKE NANOCOMPOSITE THIN FILMS FOR AUTOMOTIVE POWERTRAIN COMPONENT COATINGS
(FR) COUCHES MINCES EN NANOCOMPOSITE SEMBLABLE AU DIAMANT SERVANT A EFFECTUER LE REVETEMENT D'ELEMENTS DE TRANSMISSION AUTOMOBILE
Abstract
(EN)
A method for inhibiting wear and reducing friction of components in a powertrain assembly comprising applying to said component a coating made from a class of diamond-like solid state materials formed interpenetrating networks comprising a first network of diamond-like carbon stabilized by hydrogen, a silicon network stabilized by oxygen, and optionally at least one network made from dopant elements or dopant compounds containing elements from Groups 1-7b and 8 of the periodic table.
(FR)
Procédé permettant d'inhiber l'usure et de diminuer la friction d'éléments d'un ensemble de transmission, qui consiste à appliquer auxdits éléments un revêtement constitué par une catégorie de matériaux solides semblables au diamant composés de réseaux à pénétration réciproque, y compris un premier réseau de carbone semblable au diamant stabilisé par hydrogène, un réseau de silicium stabilisé par oxygène et, éventuellement, au moins un réseau d'éléments ou de composés dopants contenant des éléments provenant des groupes 1-7b et 8 du tableau périodique.
