Latest Patents
One of Patrick Choquet's key patents is a treatment process for depositing a layer of carbon in vapor phase. This process aims to impart resistance to frictional wear, corrosion resistance, and color to the treated article. The invention is characterized by subjecting the surface of the article to a thermochemical pretreatment under electric plasma in a vessel filled with an atmosphere containing reactive species such as nitrogen and hydrogen. These reactive species diffuse into the metal matrix of the article, forming a diffusion sublayer. Subsequently, a layer of carbon in vapor phase is deposited under electric plasma on the treated surface. The atmosphere composition for the pretreatment is gradually modified by introducing hydrocarbons and/or silanes in gaseous form while progressively reducing the partial pressures of the reactive species used during the pretreatment. The hydrocarbon atmosphere is maintained for the carbon deposition.
