Method for electrolytically coating anodized aluminum with polymers
Abstract
Abstract ELECTRICAL COUPLING WITH SAID METAL LENGTH, AND AN ELECTRICAL CONNECTION TO A CATHODE IN CONTACT WITH THE ELECTROLYTE IN THE HYDRAULIC CIRCUIT, SUCH THAT IN THE PRESENCE OF A CONTINUOUSLY SPRAYED LIQUID STREAM OF ELECTROLYTE FROM THE HEAD TO THE METAL, AN ELECTROCHEMICAL CIRCUIT IS COMPLETED VIA THE STREAM FOR CARRYING OUT THE FOREGOING METHOD. AN ALUMINUM SURFACE IS SPECIALLY ANODIZED TO PROVIDE A POLYMER-ACTIVE OXIDE LAYER, FOLLOWING WHICH A FILM-FORMING POLYMERIC ORGANIC MATERIAL IS APPLIED TO THE TREATED SURFACE AND BONDED TO IT BY MEANS OF THE POLYMER-ACTIVE OXIDE LAYER. THE APPARATUS COMPRISES MEANS FOR CONTINUOUSLY TRANSPORTING A LENGTH OF ALUMINUM METAL IN AND THROUGH A TREATMENT ZONE, A HYDRAULIC CIRCUIT INCLUDING A WETTING HEAD ADJACENT AND GENERALLY DIRECTED AT THE METAL AS IT PASSES THROUGH THE ZONE, THE CIRCUIT INCLUDING MEANS FOR CONTINUOUSLY SUPPLYING ELECTROLYTE TO THE WETTING HEAD TO DISCHARGE THE SAME AT THE PASSING METAL LENGTH, AN ELECTRICSUPPLY MEANS INCLUDING MEANS FOR ANODICALLY EFFECTING AN
