How Does Black Chrome Plating Work? (Simple Explanation) Black chrome plating is an electrolytic process in which chromium is deposited onto a prepared base layer (e.g., nickel, copper or gold) using direct current: Surface preparation: The base metal must be clean, polished and thoroughly degreased. Electroplating: The workpiece is connected as the cathode (negative pole). A suitable anode (such as graphite or platinum) is used as the positive pole. Controlled plating: Under controlled voltage and temperature conditions, chromium ions are reduced and deposit as a dark, metallic black layer. Finish: After plating, parts are rinsed and dried to reveal the final black chrome finish. This plated layer combines decorative appeal with the corrosion resistance typical of chromium coatings.
