Abstract

Le traitement thermochimique de nitruration est un traitement de surface permettant d'améliorer la durée de vie en fatigue des pièces traitées. Les dernières avancées dans ce domaine permettent de définir les paramètres technologiques du procédés en fonction des caractéristiques mécaniques en fatigue recherchées. Ce papier permet de parcourir l'ensemble des phé- nomènes physicochimiques (diffusion, précipitation, mécanique des matériaux) mis en jeux dans le traitement de nitruration, leurs modélisations multiéchelles et leurs limitations.
