Abstract (en)
[origin: WO2010040953A1] Process for manufacturing a part comprising a block (1) made of a dense material constituted of hard particles, of the same nature or of a different nature, dispersed in a binder phase, the material having a solidus temperature Ts starting from which the binder phase is liquid, characterized in that deposited over at least one portion of the surface of the block of dense material (1), is an active coating (2) constituted of a material capable of reacting chemically with the dense material when the assembly is brought above a minimum reaction temperature Tr and in that the block (1) coated with the active coating (2) is subjected to a heat treatment comprising heating, then a hold for a time tm at a hold temperature Tm greater than or equal to the minimum reaction temperature Tr followed by cooling to ambient temperature.
