Abstract: The present invention relates to a sintered body of a carbonitride alloy with titanium as main component which has improved properties particularly when used as cutting tool material in general finishing cutting operations requiring high deformation resistance in combination with relatively high toughness. This has been achieved by combining a carbonitride based hard phase of specific chemical composition with an extremely solution hardened Co-based binder phase.

Abstract: A titanium-based carbonitride cutting tool insert with superior thermal shock resistance is disclosed. This is accomplished by sintering the material under conditions where the melting process is reversed. The melt forms in the center of the material first and the melting front propagates outwards towards the surface. This leads to minimal porosity and a macroscopic cobalt depletion towards the surface. The cobalt depletion, in turn, leads to a favorable compressive residual stress in the surface zone.

Abstract: The present invention relates to a method for polishing coated cutting tools and wear parts, where at least the outer layer of the coating consists of TiN, TiC or Ti(C,N), to a high surface finish. An electrolytic method is used with an electrolyte consisting of perchloric (HClO.sub.4) or sulphuric (H.sub.2 SO.sub.4) acid, 2-50 volume %, in methanol or other organic liquid. The method is easier to control than conventional mechanical methods and renders a high surface finish over the whole coated part.
