Process for the production of corrosion resistant and decorative coatings and coating systems for substrates of light-metal or light-metal alloys

摘要

Production of highly-reflective coatings on substrates (1) made from light metals or their alloys comprises: (A) applying an adhesion-improving layer (2);applying layers of lacquer (3, 4); plasma coating with a metal (6); and (B) applying a chromium coating by electroplating. An independent claim is included for a system of layers comprising: : (A) a substrate made from light metal or light metal alloy; (B) an adhesion-improving layer; (C) a base layer of lacquer; a metal layer applied by plasma coating; and (D) a chromium coating applied by electroplating.
