| Abstract: | The recent research into the alternate
sliding bearing materials unequivocally point to the beneficial role of lead in
aluminum. But, these alloys offer a manufacturing challenge, due to wide
immiscibility gap. For sliding bearing applications, controlled porosity (size,
distribution and nature) is an important consideration, as it influences the
tribological performance through mechanical properties and spreading of lead in
aluminum matrix. In the present investigation, the effects of alloy
composition, ball to charge ratio and mixing/milling route on densification
behaviour of Al-Pb alloys processed through conventional ball milling and
attrition milling routes, using XRD, SEM and compressibility test are studied.
The resulting morphological changes of powder complexes are examined, on five
compositions of alloys to determine compaction response. The study concludes that
attrition milling is an effective method for densification of experimental
alloys. |
