This work concentrates on the preparation of AA6061/(0, 2, 4, 6, 8 wt.%) rice husk ash (RHA) aluminum matrix composites (AMCs) using compocasting and investigation of the dry sliding wear behavior by means of pin-on-disc apparatus at room temperature. The microstructures of the composites were studied using scanning electron microscopy and electron back scattered diffraction. The micrographs confirmed successful incorporation of RHA particles into the aluminum matrix. A proper distribution of RHA particles without segregation was achieved. RHA particles refined the grains of the aluminum matrix and improved the wear resistance of the composite. The influence of RHA particulate content and applied load on the worn surface and wear debris was further reported. RHA particles improved the wear resistance of the composites and reduced the damage on the worn surface. The wear mode changed with increase in the content of RHA particles and the applied load.
