Abstract:
A layered coating is disclosed herein. The layered coating includes a chromium layer, an intermediate layer of chromium and nitrogen established on the chromium layer, and an outer layer of chromium and nitrogen established on the intermediate layer. The intermediate layer has a gradually changing composition, wherein the chromium concentration decreases from an area of the intermediate layer adjacent the chromium layer towards a surface of the layered coating.
