摘要：
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 functionalized polyalkylene glycol lubricants that contain a phosphate group, phosphite group, hypophosphate group, hypophosphite group, polyphosphate group, thiophosphate group, dithiophosphate group, thiocarbamate group, dithiocarbamate group, borate group, thiosulfate group, sulfate group, a sulfonate group or combinations thereof.
