Process of modification of metallic surfaces for plasma of nitrogen and heavy hydrogen

NOVELTY – The metal surfaces modification by deuterium and nitrogen plasma has plasma pulsing to increase the hardness and corrosion, fatigue and wear resistance of the surface. The plasma is proportioned as a function of the residual oxygen in the equipment used. USE – In metallurgy.

Main Application Field

L02 (Refractories, ceramics, cement – includes manufacturing methods, limes, soil preparation for (road) building, magnesias and slags, cements, mortars, concretes, abrasives, thermal or acoustic insulation (non)oxide ceramics and ceramic composites, but not brick making, concrete mixers or casting or potters’ wheels (C04).); M13 (Coating material with metals, diffusion processes, enamelling and vitreous coatings – including coating from liquid metal or solution, spraying, cementation, cathodic sputtering, enamelling and oilfree lubricant coatings, but not coatings for the production of semiconductors (C23C, D).)
