Abstract
A tool has a main part of hard metal, cermet, ceramic, steel, high-speed steel, and a single or multilayer wear protection coating applied onto the main part by CVD and which has a thickness from 3 μm to 25 μm. The wear protection coating has at least one TiAlCNlayer with stoichiometric coefficients 0.70≤x<1.0≤y<0.25 and 0.75≤z<1.15 and a thickness from 1.5 μm to 17 μm. The TAlCNlayer has a lamellar structure with lamellae with thickness of no more than 150 nm, preferably no more than 100 nm, particularly preferably no more than 50 nm. Lamellae are made of periodically alternating regions of the TiAlCNlayer with alternatingly different stoichiometric proportions of Ti and Al, having the same crystal structure (crystallographic phase), and the TiAlCNlayer has at least 90% vol. % of face centered cubic (fcc) crystal structure.
