摘要： A coated cutting tool has a CVD coating and a substrate of a cemented carbide, wherein the metallic binder in the cemented carbide includes Ni. The CVD coating has an inner layer of TiN and a subsequent layer of TiCN. A C-activity relative to graphite in the metallic binder is lower than 0.15 and an average d electron value of the metallic binder is 7.00-7.43, wherein an interface between the substrate and the inner TiN layer is free of Ti-containing intermetallic phase.

摘要： A method of treating a sintered mining insert including cemented carbide includes the step of subjecting the mining insert to a surface hardening process. The surface hardening process is executed at an elevated temperature of or above 100° C. A mining insert is also provided, wherein the HV1 Vickers hardness measurement increase (HV1%) from the surface region, measured as an average of HV1 measurements taken at 100 μm, 200 μm and 300 μm below the surface, compared to the HV1 Vickers hardness measured in the bulk (HV1bulk), is at least 8.05-0.00350×HV1bulk.

摘要： A cutting tool includes a supporting body and a cBN or PCD cutting edge tip attached to the supporting body via a 5-150 μm braze joint. The supporting body is cemented carbide having 3-25 wt % of a metallic binder, optionally up to 25 wt % of carbides or carbonitrides of one or more elements of group 4, 5, or 6, and the rest WC. The metallic binder includes at least 40 wt % Ni, and the braze joint has, in the order from the supporting body, a first layer of TiC situated next thereto, with an average thickness of 10-400 nm, a second layer, with an average thickness of 0.5-8 μm, having in average at least 5 wt % metallic Ni, in average 25-60 wt % metallic Cu and in average 15-45 wt % metallic Ti, and a third layer, with an average thickness of 4-145 μm, having metallic Ag and metallic Cu.

摘要： The present disclosure relates to a method of treating a cutting tool of a cemented carbide or cermet substrate, wherein the cutting tool is subjected to shot peening at a temperature of or above 100° C. The cutting tool typically has a rake face, a flank face and a cutting edge extending therebetween. The shot peening is performed at least on the rake face of the cutting tool. The present disclosure also relates to a cutting tool treated with the method.
