According to said method, a plurality of layers is applied layer by layer to the peripheral surface by applying, using a PVD method, at least one metal adhesive layer based on Cr to the peripheral surface without adding nitrogen to the process gas. Nitrogen is added to the process gas while increasing the partial pressure of the nitrogen, thereby forming a CrN gradient layer on the adhesive layer, and finally at least one cover layer having a constant composition based on CrN, Cr2N or a mixture of the two phases is applied to said gradient layer.
