Art of bonding of vacuum metallized coatings

Claim 1

THE METHOD OF PREPARING A METALLIC COATED ARTICLE FROM A BODY HAVING A SURFACE PRESENTED BY A FERROUS METAL HAVING A MAJOR MATRIX COMPONENT OF FERRITIC CRYSTALLINE MOLECULAR STRUCTURE AND HAVING A REDUCIBLE OXYGENCONTAINING FILM ON SAID SURFACE, WHICH COMPRISES CLEANING THE SURFACE OF THE BODY BY AN ALKALINE SOLUTION AND THEREAFTER AS CATHODE IN AN ACID SOLUTION WHEREBY HYDROGEN ATOMS ARE STORED WITHIN THE ATOMIC LATTICE STRUCTURE OF THE SAID SURFACE METAL IN QUANTITY IN EXCESS OF THAT REQUIRED FOR REDUCING THE SURFACE OXYGEN THEREON, RINSING THE SURFACE AND DRYING THE SAME, THEN SUBJECTING THE BODY TO EVACUATION WHILE HEATING TO A TEMPERATURE OF 300 TO 1000 DEGREES F. FOR EFFECTING WITHDRAWAL OF HYDROGEN THEREFROM IN ATOMIC FORM AND REDUCTION OF THE SAID OXYGEN-CONTAINING FILM BY THE EVOLVED HYDROGEN, COOLING THE BODY TO A TEMPERATURE BELOW THAT OF THE HYDROGEN WITHDRAWAL AND BELOW 600 DEGREES F. WHEREBY FURTHER WITHDRAWAL OF HYDROGEN IS RESTRICTED, PREVENTING ACCESS OF OXIDIZING AGENTS TO SAID BODY, AND THEREAFTER WITH MAINTAINED EXCLUSION OF OZIDIZING AGENTS EXPOSING THE SAID SURFACE DURING EVACUATION AT THE LOWER TEMPERATURE TO THE VAPOR OF A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, TITANIUM, CHROMIUM AND CADMIUM AND EFFECTING DEPOSITION OF THE METAL VAPOR AS AN ADHERENT COATING ON SAID BODY.
