Abstract
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.
