PROCESSES FOR THE ELECTROLYTIC OR ELECTROPHORETIC PRODUCTION OF COATINGS; ELECTROFORMING; APPARATUS THEREFOR

Introduced: July 1974

Description

C25D covers electroplating, electroless plating, and electrophoretic deposition processes used to apply protective or decorative metallic and non-metallic coatings onto substrates. It also encompasses electroforming techniques for creating metal parts by electrodeposition and electrolytic joining methods for assembling workpieces. This subclass includes apparatus designs, process parameters, and electrolyte formulations specific to these coating and forming operations, distinguishing it from general electrochemical processes (C25A) and electrorefining or electrowinning operations (C25C).
