Abstract: A cutting tool made of a cemented carbide substrate of WC, a metallic binder phase and gamma phase is provided. The cemented carbide has a well distributed gamma phase and a reduced amount of abnormal WC grains. The cutting tool has a more predicted tool life and an increased resistance against plastic deformation.

Abstract: A method for manufacturing a wear resistant component includes the steps of providing a metallic base material and a wear resistant cemented carbide body including an anchoring portion. The wear resistant cemented carbide body is arranged such that the anchoring portion is at least partially enclosed by the metallic base material. The metallic base material and the least one wear resistant cemented carbide body is subjected to Hot Isostatic Pressing (HIP). A layer of Al2O3 or hBN is arranged between the anchoring portion and the metallic base material.

Abstract: A coated cutting tool of a cemented carbide substrate made of WC, a metallic binder phase and a gamma phase has a well distributed gamma phase and a reduced amount of abnormal WC grains. Further, the coated cutting tool is provided with a CVD coating of TiCN and an α-Al2O3 layer, wherein the α-Al2O3 layer exhibits a texture coefficient TC(0 0 12)≥7.2 and wherein in the ratio I(0 0 12)/I(0 1 14)≥1. The coated cutting tool has an increased resistance against plastic deformation. whilst maintaining toughness.

Abstract: The present invention relates to a powder mixture for three-dimensional (3D) printing of a cermet or a cemented carbide body. The powder mixture includes 65-85 wt % of porous cemented carbide or cermet particles of a median particle size (D50) of 10-35 μm, and 15-35 wt % of a dense cemented carbide or cermet particles of a median particle size (D50) of 3-10 μm. The present invention also relates to a method of making a cermet or cemented carbide body, the method including the steps of forming the powder mixture, 3D printing a body using the powder mixture and a printing binder and thereby forming a 3D printed cermet or cemented carbide green body and sintering the green body and to form a cermet or cemented carbide body.
