Abstract

Procédé de nitruration d'un composant à base de fer ferreux. Le composant est nitruré en soumettant le composant chauffé à une atmosphère d'ammoniac et ensuite à une atmosphère de gaz inerte. Application du procédé à l'acier par exemple de vilebrequin, partie de carter ou de différentiel.
