T. PratheepReddy, N. Amara Nageswara Rao

In this paper, study is on preparing hybrid metal matrix composites of Al 6061 alloy as base material by incorporating 6% SiC and varying 2 to 4 % of graphite particulates varying insteps of 2 by vortex method. The dry sliding wear test is performed using pin on disc wear test apparatus as per ASTM standards G – 99 to study the wear and frictional properties of hybrid metal matrix composite. Taguchi’s technique is implemented for designing of experiments. The analysis is performed using a L9 Orthogonal array, and Investigation to find the effect of applied load, sliding speed and track diameter on wear rate, during wear process was carried out using ANOVA technique. The wear rate was analysed using taguchi and the optimal parameters for minimizing the wear rate was determined.
