Abstract
Abstract This work focuses on manufacturing of Al + 5 Mg + 1 Gr + 4 Zircon sand, Powder metallurgy (P/M) composite along with subsequent secondary thermo-mechanical treatment and investigation of tribo-mechanical properties at room temperature. Hot extrusion process was followed as the secondary treatment for the P/M specimen prepared by double axial cold compaction and subsequent sintering. The improvement in mechanical as well as wear characteristics of the P/M specimen due to secondary treatment were analysed by comparative hardness, compression strength, transverse rupture strength and two body dry sliding wear tests. Improved bond strength due to the deformation and presence of hard Zircon particles are the key components for the improvement of different tribo-mechanical properties which are affirmed by the scanning electron microscopy. Presence of homogeneously distributed graphite particles behaves as solid lubricant hence minimizes friction coefficient during sliding wear test. Secondary treated specimens were possessed comparative lesser wear rate.
