Abstract: The present invention relates to improved matallurgical powder compositions that incorporate solid lubricants, methods for preparing and using the same, and methods of making compacted parts. Ejection properties, such as strippin g pressure and sliding pressure, of compated parts can be improved by using th e solid lubricants.The solid lubricants contain functionalized polyalkylene lubricants have the formula: R1 Q- R2 where Q is a linear or branched, polyalkylene containing from about 10 to about 200 carbon atoms, and R1 and R2 are each independently a hydroxyl group, a carboxylic acid group or a metal salt thereof, an amine group, a mono- or di- C1 to C25 alkyl substituted ami ne group, or an alkylene oxide group having the formula: -[(CH2)qO]nH where q i s from about 1 to about 7, n is from about 1 to about 100.

Abstract: The present invention relates to improved metallurgical powder compositions that incorporate solid lubricants, methods for preparing and using the same, and methods of making compacted parts. Ejection properties, such as stripping pressure and sliding pressure, of compacted parts can be improved by using the solid lubricants. The solid lubricants contain polyalkylene-polyalkylene oxide block copolymer lubricants or a combination of polyalkylene-polyalkylene oxide block copolymer lubricants and at least one additional lubricant. The polyalkylene-polyalkylene oxide block copolymer lubricants include at least one block A of a linear or branched polyalkylene chain having from about 5 to about 500 carbon atoms, and at least one block B of an alkylene oxide chain having a formula -[O(CH2)r]m-, or -[(CH2)rO]m-. The polyalkylene block copolymer lubricants can have a formula represented as A-B or A-B-A.
