| 摘要 |
<p>The invention relates to a tool with a main body made of carbide, cermet, ceramic, steel or high-speed steel and a multi-layer wear-protection coating applied on the main body using the PVD process, characterised in that the wear-protection coating comprises at least one layer (A) of TiaAl(1-a)N where 0.33≤a≤1 with a layer thickness of 20nm to 3µm and at least one layer (B) comprising a sequence of at least 4 sub-layers arranged alternately in a stack, of TibSi(1-b)N and AlcCr(1-c)N where 0.70≤b≤0.98 and 0.3≤c≤0.75 with a sub-layer thickness of 0.5nm to 15nm, and optionally further comprises a layer (C) of TidSi(1-d)N where 0.70≤d≤0.98 with a layer thickness of 50nm to 1µm, wherein the wear-protection coating can have further carbide layers, and wherein layers (A), (B) and (C) can contain up to 10 at. % of other metals, B, C and/or O per layer, depending on the process.</p> |
