Abstract

A wear and tear protection is achieved by a galvanically deposited coating on at least one of two structural components cooperating in a wear zone. The coating is a dispersion layer having a cobalt matrix and chromic oxide (Cr2O3) particles embedded in the cobalt matrix. The protective layer is produced with the aid of an electrolytic dispersion bath in which the chromic oxide particles are dispersed.
