A process for debinding a green part in which powder particles are held together by a polymer compound, the process comprising a heat treatment of the green part under a non-oxidizing atmosphere, and a thermochemical treatment of the green part under an oxidizing atmosphere for a duration less than or equal to a predetermined duration, the heat treatment and the thermochemical treatment being carried out in a same enclosure and at temperatures less than the sintering temperature (Tf) of the powder particles.
