摘要： The invention relates to a cutting tool having a substrate base body and a single or multi-layered coating attached thereupon, wherein at least one layer of the coating is a metal oxide layer produced in the PVD process or in the CVD process and the metal oxide layer has a grain structure wherein there is structural disorder within a plurality of the existing grains that are characterized in that in electron diffraction images of the grains, point-shaped reflections occur up to a maximum lattice spacing d
GRENZ and for lattice spacing greater than d
GRENZ no point-shaped reflections occur, but rather a diffuse intensity distribution typical for amorphous structures.

摘要： The invention relates to a method for producing a nanostructured, in particular, ceramic-type functional coating (17) on a substrate (16). At least one plasma source (11, 12) generates a pulsed plasma (13, 14), by means of which a matrix phase (30) with at least one nanoscalar interstitial phase (31) embedded therein is deposited on the substrate (16), with the aid of the introduction of a material. Preferably, a plurality of temporally correlated or synchronised pulsed plasma sources (11, 12) is used. The invention also relates to a nanostructured functional coating (17), produced in particular according to said method, which is devoid of chlorine and/or sulphur and contains at least one metal and/or at least one element selected from the group comprising oxygen, hydrogen, nitrogen, carbon, helium, argon and neon.

摘要： The present invention relates to a coated cutting tool comprising a substrate and a coating comprising a first, a second and a third layer, wherein
i) the first layer is a (Ti, AI)N layer adhered to the substrate, said first layer having
a. an atomic ratio AI/(Ti+AI) of 0.3 to 0.65
b. a fracture toughness ranging from 3.5 to 6MPa √ m
c. a substantially homogeneous residual stress σ 1 in the range from +100 to -1000 MPa

ii) the second layer is a (Ti, AI)N layer adhered to the first layer having
a. an atomic ratio AI/(Ti+AI) of 0.3 to 0.85
b. a residual stress σ 2 ranging from about σ 1 at the interface with the first layer to σ 3 at the interface with the third layer, wherein σ 2 gradually increases from the interface with the first layer towards the interface with the third layer adhered to the second layer, wherein the residual stress σ 2 at the interface with the third layer is substantially the same as in the third layer

iii) the third layer is composed of a nitride of one or more elements belonging to group 4, 5 or 6 of the periodic table of elements, or a nitride of Al and/or Si together with one or more elements belonging to group 4, 5 or 6 of the periodic table of elements, said third layer having a substantially homogenous residual stress σ 3
