Abstract: The present invention describes a coated cutting tool for metal machining and a process for producing such tools. The coating is composed of one or more layers of refractory compounds of which at least one layer consists of nanocrystalline aluminum spinel of the type (Me)xAl2O3+x where Me is a second metal and 0

Abstract: The present invention relates to a process for producing a coated cutting tool consisting of a coating and a substrate, wherein at least one refractory layer consisting of fine-grained, crystalline gamma -Al>2 3 . The substrate temperature is in the range of 400 to 700 DEG C and the flux of impinging particles onto each individual substrate is cyclically interrupted.
