Abstract:
A tool includes a base body of hard metal, cermet, ceramics, steel or high speed steel and a multi-layer wear protection coating deposited thereon by a PVD process. The wear protection coating has a first coat deposited on the base body having a composition of TiaAl(1-a)N, wherein 0.4≤a≤0.6, and a coating thickness of 0.5 μm to 4 μm, and a second coat deposited on the first coat. The second coat includes a sequence of 10 to 80 first and second layers alternatingly arranged one on top of each other. Each of the first and second layers has a thickness of 5 to 100 nm. Each first layer includes nitrides of the elements Ti, Al, Cr and Si, and each second layer has a composition of TixAl(1-x)N, wherein 0.4≤x≤0.6. The first and second coats have up to 10 at-% of further metals, B, C and/or O as impurities in each layer.

Claim (Index 1):
A tool comprising:\n a base body selected from hard metal, cermet, ceramics, steel and high speed steel; and a multi-layer wear protection coating deposited on the base body by a PVD process, wherein the wear protection coating includes: a first coat deposited on the base body and having the composition Ti a Al (1-a) N wherein 0.4\u2264a\u22640.6 and a coating thickness of 0.5 \u03bcm to 4 \u03bcm, a second coat deposited on the first coat and including a sequence of 10 to 80 of each of first layers and second layers alternatingly arranged on top of each other, wherein each of the first and second layers has a layer thickness of from 5 nm to 100 nm, wherein the first layer includes nitrides of elements Ti, Al, Cr and Si, and wherein the second layer has a composition of Ti x Al (1-x) N, wherein 0.4\u2264x\u22640.6, and at least one further hard material coat disposed above the second coat, and wherein the first and second coats due to the manufacturing method include up to 10 at-% of metals, B, C and/or O as impurities in each layer.
