ABSTRACT:
Ironing, drawing and/or other non chip-producing process is used to form a metal workpiece into an article which is then coated with a protective layer. The lubricating agents used in the non-chip-producing process are removed from the surfaces of the formed article in conjunction with the coating of the article with the protective layer. This is done by dissolving the lubricating agents in the liquid which is used in the application of the protective layer and which contains one or more bonding agents which form the protective layer after the treatment is complete. In one preferred embodiment, at least that protective layer which is closest to the material of the container is applied by electrolytic deposition.
