Claim:
1. A method for producing oxidic layers by means of physical vapor deposition (PVD), comprising: forming a powder-metallurgical target comprising a composition from the group consisting of A1V, with Al ranging from 92 at % to 97 at % and V ranging from to 3 at % to 8 at %, and AlCr, with Al ranging from 80 at % to 90 at % and Cr ranging from 10 at % to 20 at %, the composition being chosen in such a manner that during heating in a transition from room temperature into a liquid phase no phase boundary of purely solid phases, based on a phase diagram of a molten mixture of the composition, is crossed; and vaporizing the powder-metallurgical target by means of cathodic arc vaporization in a reactive atmosphere comprising oxygen as reactive gas in order to produce the oxidic layers.
