Abstract: A method is disclosed for coating, by means of a chemical vapor deposition (CVD) technique, a part with a coating (PAO) for protecting against oxidation. The method enables the preparation of a refractory coating for protecting against oxidation, having a three-dimensional microstructure, which ensures the protection against oxidation at a high temperature, generally at a temperature above 1200° C., for materials that are sensitive to oxidation, such as composite materials, and in particular carbon/carbon composite materials.

Abstract: A method for preparing a protective coating against oxidation on at least one surface of at least one part made of at least one material capable of being oxidized, wherein the following successive steps are carried out: a) each of the particles of a powder made of a first ceramic selected from refractory ceramics and ceramics which resist oxidation, is coated with at least one layer selected from layers made of a refractory ceramic, layers made of a ceramic which resist oxidation, and layers made of a refractory metal, provided that the coating comprises at least one ceramic which resists oxidation, and at least one refractory ceramic or metal; b) the powder is deposited onto the surface to be coated of the part; c) sintering of the powder is achieved on the surface of the part by a Spark Plasma Sintering (SPS) Method; d) the part is cooled; e) the cooled part, coated on at least one of its surfaces with a protective refractory monolayer coating against oxidation, with a three-dimensional microstructure, i
