Abstract

On porte la pièce, au moins dans une zone superficielle, à une température comprise entre 300 et 460°C. En maintenant une atmosphère gazeuse renfermant un élément interstitiel à l'état activé, à une pression comprise entre 0,5 et 200 mbars, au contact de la surface de la pièce, on fait pénétrer et diffuser l'élément interstitiel dans la couche superficielle de la pièce de manière à obtenir, dans la couche superficielle, une solution solide exempte de précipités, renfermant de 5 à 50 atomes % de l'élément interstitiel. L'invention s'applique en particulier au durcissement des aciers inoxydables par le carbone.
