Abstract:
1. Arc evaporation deposited PVD layer system for the coating of workpieces, encompassing at least one mixed-crystal layer of a multi-oxide of the following composition: where Me1 and Me2 each represent at least one of the elements Al, Cr, Fe, Li, Mg, Mn, Nb, Ti, Sb or V and the elements of Me1 and Me2 differ from one another, wherein 1-x and x represent a stoichiometry of the Me1 Me2 alloy, characterized in that the crystal lattice of the mixed-crystal layer exhibits a corundum structure which in a spectrum analyzed by x-ray diffractometry is characterized by at least three of the lines associated with the corundum structure, wherein said mixed-crystal layer a multi-oxide comprises areas of said at least one element.
