  • Method for preparing a coating for protecting a part against oxidation
    Patent number: 9493873
    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.
