Abstract

Body of cemented carbide or cermet coated with a diamond layer has a surface zone of depth 2-10 micron, preferably about 8 micron, at the interface with the diamond coating where the average binder content is at least 20% preferably about 50% lower than the nominal content. The coercive force of the body is at least 10%, preferably at least 20%, and especially about 30% higher than that for a reference body of the same WC phase grain size and binder content subjected to standard sintering and has a saturation magnetisation at most 95%, preferably at most 85%, and especially at most 70% of that of the reference body. Method comprises post-sintering an eta-phase containing cemented carbide body at 1400-1510 deg C, preferably about 1450 deg C, in an H2-containing carburising atmosphere prior to diamond coating, so as to convert eta-phase in the surface zone to carbides and binder phase.
