TOOL HAVING CVD COATING

摘要

The invention relates to a tool having a base body made of carbide, cermet, ceramic, steel or high speed steel and a single or multiple layer wear-protection coating applied thereto in the CVD process, wherein the wear-protection coating has at least one Ti1-xAlxCyNz layer having stochiometric coefficients 0.70 < x < 1, 0 < y < 0.25 and 0.75 < z < 1,15, wherein the Ti1-xAlxCyNz layer has a thickness in the range from 1 μm to 25 μm and has a crystallographically preferred orientation, which is characterized by a ratio of the intensities of the x-ray diffraction peaks of the crystallographic {111} plane and the {200} plane, wherein l{111} / I{200} > 1 +h (In h)2, wherein h is the thickness of the Ti1-xAlxCyNz-layer in "μm."
