The invention concerns a method for making a diamond-coated composite material comprising deposition on a substrate of an intermediate layer and deposition on the intermediate layer of a diamond coating. The invention is characterised in that the intermediate layer is an expansible layer capable of producing chemical bonds with the substrate while chemically developing during deposition of the diamond coating. The invention is applicable to a large number of articles and components made of diamond composite.
L'invention concerne un procédé de fabrication d'un matériau composite diamanté du type comportant le dépôt sur un substrat d'une couche intermédiaire et le dépôt sur la couche intermédiaire d'un revêtement diamanté. Il est caractérise en ce que la caliche intermédiaire est une couche évolutive susceptible d'engager des liaisons chimiques avec le substrat tout en pouvant évoluer chimiquement lots du dépôt du revêtement de diamant. Application à de nombreux articles ou pièces en matériau composite diamanté.
