Abstract:
A method of treating metal parts to provide durable and rust-inhibiting coatings is described. The application method can be used to treat single parts or bulk barrel processing of parts. The method comprises the steps of (a) phosphating the metal parts with an aqueous metal phosphating solution, (b) electrophoretically depositing a siccative organic coating on the phosphated metal parts, and (c) applying a corrosion inhibiting film of oil as a seal coat.
