摘要: The present invention relates to a method for adjusting the brightness L* of an electroplated chromium layer, in particular of a dark electroplated chromium layer. The method includes an aqueous trivalent chromium electroplating bath comprising colloidal particles and/or agglomerates thereof and a step of fully or partially removing same with optionally adding colloidal particles.

摘要: A method of treating a substrate, wherein the substrate comprises a layer deposited from a trivalent chromium electrolyte, is described. The method includes the steps of providing an anode and the chromium(III) plated substrate as a cathode in an electrolyte comprising (i) a trivalent chromium salt; and (ii) a complexant; and passing an electrical current between the anode and the cathode to passivate the chromium(III) plated substrate. The substrate may be first plated with a plated nickel layer so that the chromium(III) plated layer is deposited over the nickel plated layer.
