Abstract:
A method of making a metal based compacted component comprising the steps of:(a) providing a metallurgical powder composition comprising at least about 85 percent of a metal-based powder; (b) providing an external lubricant composition, wherein the external lubricant composition comprises at least about 10 percent by weight, based on total weight of the external lubricant composition, of high melting point polymeric wax lubricant having a melting point range beginning, at a temperature greater than about 100 degrees Centigrade; (c) applying the external lubricant composition to interior walls of a compaction die in an amount sufficient to reduce the stripping and sliding pressures upon ejection of a metal based component; and (d) compacting the metallurgical powder composition in the die at a compaction pressure sufficient to form a metal component.
