Abstract
A coated body having a multi-layer of &kgr;-Al2O3 and or &ggr;-Al2O3 or TiN applied by MTCVD (Medium Temperature Chemical Vapor Deposition) is disclosed. The multi-layers can be interspersed with layers of Ti(C,N) which can also be applied by MTCVD. The body which is coated is preferably a cemented carbide, cermet, ceramic and/or high speed steel and may be used as a metal cutting insert.
