not only to lubricate the crack faces and reduce the crack face friction coefficient but also to generate a pressure....

Addition of lubricant in the form of admixed with powder reduces friction between die wall and powder during compaction of P/M parts. However, it has detrimental effect on mechanical properties. On the other hand, warm compaction of powders improves...

Abstract

The influence of sintering temperature, heat treatment and lubricant on the wear rate of warm compacted Fe–3%Cr–0.5%Mo–0.45%C Astaloy steel P/M alloy [Astaloy CrM] was investigated using dry sliding wear test, X-ray diffraction...
