The invention relates to a part made of a ceramic matrix composite comprising a fibrous reinforcement made of carbon or ceramic fibers, and a mainly ceramic sequenced matrix comprising first matrix layers made of a crack deviator alternating with second matrix layers made of a ceramic. An interphase coating is interposed between the fibers and the matrix, the interphase coating adhering to the fibers and to the matrix and being formed from at least one sequence consisting of a first elementary layer made of carbon, which is optionally doped with boron, surmounted with a second elementary layer made of a ceramic, the external elementary layer of the interphase coating being a ceramic layer the external surface of which is formed by ceramic grains the size of which essentially lies between 20 nanometers and 200 nanometers, with the presence of grains larger than 50 nanometers in size providing the external surface with a roughness ensuring mechanical bonding with the adjacent matrix phase.
