Abstract

Le procédé selon l'invention consiste à porter les pièces à traiter à une température supérieure à 500°C à l'intérieur d'une enceinte dont l'atmosphère est maintenue à une pression inférieure ou égale à 0,1 mbar, puis à injecter sur les pièces un gaz de traitement, la pression s'établissant alors à une valeur inférieure à la pression atmosphérique pendant une durée pouvant aller de quelques dizaines de minutes à vingt quatre heures ou plus en fonction de la profondeur de traitement désirée.
L'invention s'applique au traitement de pièces en titane ou en zirconium.
