Abstract: A process for manufacturing a composite material part including a particulate reinforcement densified by a ceramic matrix, the process including: formation of a blank of the part to be manufactured by shaping a mixture including a binder, first ceramic or carbon particles intended to form the particulate reinforcement of the part and second ceramic or carbon particles distinct from the first particles, removal or pyrolysis of the binder present in the blank to obtain a porous preform of the part to be manufactured, and infiltration of the porosity of the preform by a molten composition including a metal in order to obtain the part.

Abstract: A part made of composite material includes fiber reinforcement densified by a ceramic matrix. The part presents an outside surface and is coated over at least a portion of its outside surface by a surface coating in solid form including an alloy of silicon and nickel presenting a content by weight of silicon lying in the range 29% to 45%, or an alloy of silicon and cobalt.
