Abstract: The invention relates to a method for depositing a carbon-based material from a target onto a metal substrate, by ion-assisted cathode sputtering.
According to the invention, the ratio between the flow of ions that is directed toward the substrate and the flow of neutral carbon atoms that is directed toward the substrate is adjusted to between 1.7 and 3.5; and a bias voltage of between −35 V and −100 V is applied to the substrate.

Abstract: A process for generating nanoparticles on the surface of a substrate includes a step of providing the substrate made of a material including at least one element from columns 4, 5, 13 and 14 of the periodic classification, and at least one noble or transition metal; a step of irradiating the substrate by laser, with a pulse duration between 1 fs and 100 ps, a pulse between 0.01 J/cm2 and 100 J/cm2, a wavelength between 100 nm and 5000 nm, and a number of pulses per point between 1 and 1000; and a step of generating at least one nanoparticle on the surface of the substrate, the at least one nanoparticle including at least the noble or transition metal, and having a different chemical composition from that of the substrate. Also disclosed is a part including such nanoparticles.

Abstract: The invention relates to a metal part comprising a metallic substrate (S) having an outer surface coated with a layer of carbon-based material (M). According to the invention, the layer of carbon-based material:—is of “DLC” amorphous carbon type, from the a-C family; • comprises less than 3 at % of oxygen within the layer of carbon-based material; • does not contain hydrogen, nitrogen, or doping elements.
