Abstract

An anode for use in electroforming copper foil is formed by depositing a multilayer coating on a substrate of a film forming metal. At least one interior layer consists essentially of substantially pore free platinum which is applied electrolytically to a thickness of at least about 5 micrometers (about 200 microinches), and then densified by heat treating in an oxygen containing atmosphere at from 600 to 775 DEG C. At least one of the exterior layers consists essentially of at least 97% iridium oxide and up to about 3% rhodium oxide, which is applied by thermal decomposition of thermally decomposable platinum group metal compounds in an oxygen containing atmosphere at a temperature of not more than about 600 DEG C.
