Abstract:
An object including a chromium-based coating on a substrate and a method for its production are disclosed. The chromium-based coating having a first layer on the substrate, wherein the first layer has a top surface on the opposite side to the substrate and includes fissures within the first layer, and wherein the material of the first layer is predominantly formed of chromium and chromium carbide; the chromium-based coating further having a second layer on the first layer, the second layer at least partially filling the fissures in the first layer and at least partially covers the top surface of the first layer, wherein the material of the second layer is selected from a group consisting of: chromium oxide, carbon, and a combination of chromium oxide and carbon.
