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 13):
A process for manufacturing of a tool comprising:\n providing a base body made of hard metal, cermet, ceramics, steel or high-speed steel; depositing a multi-layer wear protection coating on the base body by a PVD process, such as an-arc vapor deposition, wherein on a surface of the base body a first coat is deposited, the first coat having a composition TiAlN, wherein 0.4\u2264a\u22640.6 and a coating thickness of from 0.5 \u03bcm to 4 \u03bcm; and depositing on the first coat, a second coat having a sequence of 5 to 100 of each of alternatingly, one on top of each other first layers and second layers, a thickness of each of the first and second layers being of from 5 nm to 100 nm, wherein the deposition of the first layers is effected by the deposition of alternatingly, on top of each other, arranged sub-layers having the compositions Ti y Si (1-y) N and Al z Cr (1-z) N, respectively, wherein 0.70\u2264y\u22640.98 and 0.6\u2264z\u22640.8 and with a thickness of each of the sub-layers being from 0.5 nm to 15 nm, and wherein the second layer has the composition Ti x Al (1-x) N wherein 0.4\u2264x\u22640.6.
