  • Method for texturing DLC coatings, and textured DLC coatings thus obtained
    Patent number: 9040141
    Abstract: This method for texturing a DLC coating comprises depositing a single layer of balls or spheres on the free surface of the DLC coating; dry-etching the DLC coating using oxygen plasma; and lastly, cleaning the surface of said coating by eliminating the balls or spheres.
    Type: Grant
    Filed: June 9, 2010
    Date of Patent: May 26, 2015
    Assignee: Commissariat a l'Energie Atomique et aux Energies Alternatives
    Inventors: Caroline Chouquet, Cédric Ducros, Jérôme Gavillet, Frédéric Sanchette
  • Method of producing a hydrogenated amorphous carbon coating
    Patent number: 8367207
    Abstract: The invention relates to a hydrogenated amorphous carbon coating and to a method for the production thereof. It also relates to devices having such a coating. The method of the invention consists in producing a hydrogenated amorphous carbon coating comprising at least two layers of hydrogenated amorphous carbon, each of said layers having chemical compositions and physical and mechanical properties that are identical, and with thicknesses that are identical or different. The coating of the invention finds many applications, in particular in the mechanical field for parts subject to considerable wear and rubbing problems. It may also be applicable, in particular, in the field of surgical implants and in the MEMS (microelectromechanical systems) field.
