Abstract
A metalworking die has a soft metal plating on its contact surfaces. The plating produces a continuous lubricant supply which is only depleted slowly when employed in a hot metalworking operation. In forming a near-net-shape part using this die, the metalworking piece is coated with a glass lubricant. A temporary lubricant of graphite is also sprayed on the coated die.
