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. |
