A PVD layer system for coating workpieces comprises at least one mixed crystal layer of a polyoxide with the following composition: (Me1 <SUB>1-x</SUB>Me2<SUB>x</SUB>)<SUB>2</SUB>O<SUB>3</SUB>. Me1 and Me2 are at least one of the elements Al, Cr, Fe, Li, Mg, Mn, Nb, Ti, Sb or V. The elements of Me1 and Me2 are each different. The crystal lattice of the mixed crystal layer in the PVD layer system has a corundum structure, which is characterized by at least three lines associated with the corundum structure in a spectrum of the mixed crystal layer, measured by means of X-ray diffractometry. A vacuum deposition method for the production of a mixed crystal layer of a polyoxide and accordingly coated tools and components are also disclosed. |
