Patent

CA 2635020

The invention relates to a method of coating a cemented carbide or cermet substrate body by means of PVD, in which the fully sintered substrate body is subjected without further intermediate treatment before PVD coating to a blasting treatment using a particulate blasting agent until the zone close to the surface of the substrate body has a residual stress which is at least essentially of the same magnitude as the residual stress present in the single or first applied PVD layer. The invention further relates to such a coated cemented carbide or cermet body, in particular in the form of a cutting tool.

L~invention concerne un procédé de revêtement d~un corps de substrat en métal dur ou en cermet au moyen du PVD, dans lequel le corps de substrat déjà fritté sans autre traitement intermédiaire avant le revêtement par PVD est soumis à un traitement par jet au moyen d~un moyen de projection granulaire jusqu~à ce que la zone proche de la surface du corps de substrat présente une contrainte résiduelle qui est au moins sensiblement égale à la contrainte résiduelle qui est présente dans la seule ou la première couche de PVD appliquée. L~invention concerne en outre un tel corps en métal dur ou en cermet revêtu, en particulier sous la forme d'un outil pour enlever les copeaux.
