Abstract
The tribiological behaviour of aluminium hybrid composites reinforced with Silicon carbide (10 wt.%) and Fly ash (FA 0, 5, 10 and 15 wt.%) fabricated using powder metallurgy technique was investigated. Wear tests were performed on pin on disc machine to assess the tribiological behaviour of composites and to determine the optimum volume fraction of fly ash for its minimum wear. Wear loss reduces with increase in fly ash weight fraction and minimum wear rate was attained at 10 wt.% fly ash. The influences of sliding distance, sliding speed and applied load were studied with test based on full factorial design of experiments (DOE). Analysis of variance (ANOVA) was used to evaluate the percentage contribution of each sliding wear process parameters on wear loss. From the ANOVA approach, it was concluded that wear loss is mainly influenced by sliding distance followed by sliding speed and applied load.
