ABSTRACT:
The present invention discloses an improved method for compacting powdered materials, including ferrous alloys, non-ferrous metals or non-metal powders, wherein the improved method includes the use of an improved lubricant during the compaction process. The improved lubricant includes vinyl halides, generally, and polytetrafluroethylene, specifically. In a preferred embodiment of the present invention, 0.2 to 0.6 wt. % of the vinyl halide is added to the powdered form of the compactable material before the compaction and sintering of the compactable material.
