Journal of the institution of engineers (India): Series CSummary: Al-6061 alloys are utilized to make a variety of automotive parts. During operation, the engine components are subjected to sliding and abrasive wear against the counter surface. This work outlines efforts to include fly ash and rice husk ash into aluminium castings to reduce the material content, cost, and weight of certain industrial components while improving tribological properties. The dry sliding wear behaviour of aluminium based metal matrix composite reinforced with Fly ash and Rice husk ash was analyzed by varying different particle sizes as 0–53 µm, 54–74 µm, and 75–105 µm. Stir casting route was used to develop the composites. Pin-on-disc setup was used to analyse the dry sliding wear behaviour and mechanism of the developed composites at ambient to elevated temperature. Response surface methodology was used to analyse the combined effects of different process parameters. The influence of various parameters such as sliding velocity, sliding distance, temperature load, and particle size was investigated by analysis of variance (ANOVA). It was observed from the wear results that the particle size, load and temperature are having more influence on dry sliding wear followed by sliding velocity and sliding distance. Also it was observed that the wear resistance and coefficient of friction were superior in composites reinforced with coarse particle size 75–105 µm compared to composites with fine particle sizes. During sliding wear, the presence of stable oxides in the microstructure improved wear resistance. The oxides Al2O3 and SiO2 strengthen the matrix by producing strong boundaries and increasing wear resistance.
