Abstract
By cathode sputtering in a reactive environment, a coating of a solid solon of chromium and an element such as nitrogen, carbon, phosphorus, boron or silicon is deposited. The content of the above element is higher than the saturation limit of the solid solution in chromium. It ranges between T.sub.m =0.2% and T.sub.M =3% by weight for carbon and between T.sub.m =0.04% and T.sub.M =3.5% by weight for nitrogen.
