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.
