Abstract

L'invention concerne un corps de coupe d'outil (10) destiné à être soudé à un corps de base d'outil (1) composé d'acier. Le corps de coupe d'outil (10) présente une partie travail (20) composée de céramique contenant du silicium et une partie liaison (30) composée d'un métal dur à base de WC, d'un matériau de base Mo ou d'un matériau de base W. La partie travail (20) et la partie liaison (30) sont assemblées l'une à l'autre par liaison de matière au niveau d'au moins deux zones de surface (21a, 21b) de la céramique non parallèles l'une à l'autre. La partie liaison (30) présente au moins une surface de jonction (19) pour l'assemblage par liaison de matière par soudage à un corps de base d'outil (10).
