Abstract: COPPER OR IRON ARE SECURELY BONDED TO TITANIUM OR TANTALUM SUBSTRATE METAL BY INITIALLY SUBJECTING THE SUBSTRATE METAL TO IONIC BOMBARDMENT IN WHICH THE SUBSTRATE METAL PERFORMS THE ROLE OF A CATHODE AND THEN TO CATHODE SPUTTERING IN WHICH THE SUBSTRATE METAL PERFORMS THE ROLE OF AN ANODE, AND THE COPPER OR IRON THE ROLE OF A CATHODE. THEREAFTER, THE BONDED COPPER OR IRON IS SUPPLEMENTED BY ADDITIONAL DEPOSITS BY CONVENTIONAL MEANS SUCH AS ELECTRODEPOSITION, ETC. SUPERIOR INDUSTRIAL PRODUCTS RESULTING FROM THE PROCESS ARE USEFUL AS ANODES IN ELECTROLYSIS CELLS AND AS HEAT EXCHANGERS.
