Abstract
There are numerous ways to produce Metal Matrix Composites (MMC). In the present study, a new approach has been designed with the combination of vacuum arc melting and powder metallurgy to produce non-equilibrium MMCs. The Al–2%ZrB2 homogenous composite mixture was compacted in uniaxial direction and used as raw material for vacuum arc melting. The green compacts are subjected to high temperature within a short span of time. The melts were assured for homogenous composition by melting from different faces. Hardness of the composite was measured and which appeared to be higher than its powder metallurgy counterpart. The XRD patterns were analyzed for the phases present in the composite after melting. The composite has been tested to evaluate the corrosion rate through potentiodynamic polarization study.
