“…In the past, researchers have concentrated on the optimization of the process parameters influencing wear rate with respect to various MMCs, and have considered the composition of reinforcements and the stirring speed as the critical issue for the enhancement of the properties [10][11][12]. Prasath et al [13] studied the wear properties of AA6061-SiC-B 4 C-Fly Ash composites fabricated by stir casting. The levels of experimental factors like load, sliding speed and sliding distance are sequenced and designed by response surface methodology.…”

The wear characteristics of Aluminium AA 5083/SiC/Fly ash functional composites under different load conditions are an important aspect to assess the inoculation of fly ash for enhancing the functionality of the Aluminium composites with respect to its tribological behaviour and its influence on wear. Current work is majorly aimed at the development of AA 5083/SiC functional composites inoculated with fly ash using stir casting method for different blends of the reinforcements (2.5, 5 & 7.5 wt. %). Wear characteristics of these fabricated composites has been investigated considering various process parameters and influence of each parameter on wear rate was discussed. Based on different wear regimes obtained after characterization of the samples at different load conditions, Analysis of Variance (ANOVA) is carried out for each blend of the samples. The results have given sufficient substantiation to the fact that wear rate decreases with the inoculation. Results conferred that micro segregation (coring) of SiC and uniform dispersion of fly ash in the matrix enhances its tribological characteristics.
