摘要： The invention relates to a method for smoothing a corrugated, rough surface of a part made from a ceramic matrix composite material. According to the invention, a ceramic coating is formed on the surface of the part by means of the following steps, namely: application (20) of a liquid composition on the surface of the part, said composition containing a ceramic precursor polymer and a solid refractory filler; crosslinking (40) of the polymer; and conversion (50) of the crosslinked polymer into ceramic by means of heat treatment. The method also includes the impregnation of the ceramic coating with a liquid metal composition (60).

摘要： The process comprises the following steps: formation of a porous fibrous reinforcing structure; introduction of powders into the pores of the fibrous structure, said powders containing constituent elements of the matrix of the composite; and formation of at least the main part of the matrix from said powders, by reaction between the powders and/or with at least one additional element supplied; the powders introduced into the fibrous structure and the element(s) supplied comprising elements for forming at least one discontinuous healing matrix phase comprising a boron compound and at least one discontinuous matrix phase comprising a compound having a crack-deflecting lamellar structure. The formation of at least the main part of the matrix is obtained by the chemical reaction between the powders introduced into the fibrous structure and at least one additional element supplied, or by sintering the powders.
