Title (EN) CEMENTED CARBIDE BODY HAVING A WEAR RESISTANT SURFACE LAYER
(FR) CORPS EN CARBURE CEMENTE AYANT UNE COUCHE SUPERFICIELLE RESISTANTE A L"USURE
Abstract: front page image
(EN)By applying very thin layers of wear resistant materials to the surface of a hard metal body, its life can be essentially improved used as a cutting tool in metal cutting. In order to obtain improvements of the properties by means of such layers there is needed a securing adhesion or adherence between layer and substrate. The invention relates to such a hard metal body, to which one or more additive metals have been added, which can selectively be oxidized and thereby form a wear resistant layer of improved properties of adherence and ductility.
(FR)En appliquant des couches tres fines de materiaux resistant a l"usure sur la surface d"un corps metallique dur, on peut prolonger sensiblement sa duree de vie en tant qu"outil de coupe de metaux. Afin d"ameliorer les caracteristiques du materiau au moyen de ces couches il est necessaire d"assurer l"adhesion entre la couche et le substrat. Sur un tel corps metallique dur on ajoute un ou plusieurs metaux, qui peuvent etre selectivement oxydes et peuvent ainsi former une couche resistante a l"usure presentant des proprietes ameliorees d"adherence et de ductilite.
