CONTINUOUS COATING APPARATUS FOR ELECTROCERAMIC COATING OF METAL COIL OR WIRE

摘要

A system and a process for continuously electrolytically coating a light metal coil is provided. The system includes a bath containing a precursor for an electroceramic coating on a light metal coil and containing a cathodic connection, at least one motor connected to at least one motive assembly to impart movement to the coil. A power source provides voltage and current to the coil through the electrification device, and through the coil in the bath to the cathode connection via the aqueous electrolytic solution. The process includes electrifying bare coil with a voltage and a current, passing the electrified bare light metal coil through a bath having a cathodic connection and containing an aqueous solution with a precursor for an electroceramic coating, and electrochemically reacting the light metal coil with the precursor thereby generating a coated light metal coil having an electroceramic coating on at least one surface.
