Electrolytic processes and electrodes therefor

摘要

A method of forming a composite body comprising an elongate body of a film-forming metal such as titanium surrounded by a sheath of a precious metal which comprises the steps of forming an assembly of the two materials, surrounding the same with a sleeve of a solid deformable protection and lubrication material and extruding the assembly to produce the elongate body. The assembly may have a core of high conductivity metal and may be formed into electrodes for use in electrolytic cells such as electro-winning etc.
