Abstract
The invention relates to a method for producing a coated substrate body by chemical vapor deposition at least on one layer made of a carbonitride of a metal of IVa-Vla-groups of the periodic table, wherein a monocyclic hydrocarbon is used in the gas atmosphere during the deposition, in addition to a nitrile. According to the invention, the thus produced coated substrate body has a high degree of hardness and is used, preferably, in cutting operations where the cutting speeds are ≧250 m/min.
