Abstract: A coated tool disclosure includes a base body and a coating layer. The coating layer includes crystals having a cubic structure. The coating layer has a striped structure in cross-sectional observation by a transmission electron microscope. The striped structure has two layers alternately located in a thickness direction. The two layers contain Si and at least one metal element. The two layers each contain crystals having the cubic structure. When a lattice constant of a crystal having the cubic structure in one layer of the two layers is referred to as a first lattice constant and a lattice constant of a crystal having a cubic structure in the other layer of the two layers is referred to as a second lattice constant, a difference between a magnitude of the first lattice constant and a magnitude of the second lattice constant is greater than 0% and 0.1% or less.

Abstract: The invention relates to a method of coating a cemented carbide or cermet substrate body by means of PVD, in which the fully sintered substrate body is subjected without further intermediate treatment before PVD coating to a blasting treatment using a particulate blasting agent until the zone close to the surface of the substrate body has a residual stress which is at least essentially of the same magnitude as the residual stress present in the single or first applied PVD layer. The invention further relates to such a coated cemented carbide or cermet body, in particular in the form of a cutting tool.
