    Abstract: A coated cutting tool comprising a substrate and a coating layer formed on a surface of the substrate, the coated cutting tool having a rake surface and a flank, in which the coating layer includes an α-type aluminum oxide layer, wherein: the α-type aluminum oxide layer has, on an opposite side to the substrate, a first interface, being the rake surface or a surface substantially parallel to the rake surface, a second interface, being the flank or a surface substantially parallel to the flank, and an intersecting edge between the first interface and the second interface; and a residual stress value (unit: GPa) measured near each of the first and second interfaces increases continuously or stepwise as a measurement position for the residual stress value becomes distant from the intersecting edge with distances of 10 μm, 50 μm, 100 μm, 150 μm and 200 μm.(In the above formulae, σ11 denotes a residual stress value (MPa) in a direction parallel to the intersecting edge, σ22 denotes a residual stress value (MPa) in a direction orthogonal to the intersecting edge, and each of the residual stress values is a value measured by a 2D method.)

    Abstract: A method for forming a chromium nitride coating over a substrate to provide a chromium nitride coated article, and the resulting chromium nitride coated article, each use a bilayer chromium nitride containing material layer. The bilayer chromium nitride containing material layer includes: (1) a first chromium nitride material layer having a first thickness, a first uniform chromium concentration and a first uniform nitrogen concentration located and formed closer to a substrate which provides the article; and (2) a second chromium nitride material layer having a second thickness, a second increasingly graded chromium concentration and a second decreasingly graded nitrogen concentration located and formed upon the first chromium nitride material layer. This particular bilayer chromium nitride containing material layer provides the article with superior reflectivity and crack resistance.

    Abstract: One example of the invention relates to an indexable insert comprising a base that has flanks and at least one face. According to one example of the invention, primarily the face(s) of the indexable insert, but not the flanks thereof, are coated with a very thick layer (e.g. thicker than 50 μm) of a hard material in a PVD process.
