Processing and wear characterisation of self-lubricating AA6082/TiC/Gr composites

Abstract

The manuscript presents wear characteristics modelling of AA6082/TiC/Gr composites using rotatable central composite design of response surface methodology. Experiments were conducted at room temperature using pin on disc apparatus. Wear rate model was established as a function of cast sample, applied load and sliding velocity. The analysis of the variance (ANOVA) results revealed ‘Model’ as ‘Significant’ and ‘Lack of fit’ is ‘Not significant’, indicating a good model. The results also show applied load as the most influencing factor while cast sample the least factor affecting the wear rate. The combined effect of cast sample and applied load affects the wear rate more as compared to other combinations. Scanning electron microscopy (SEM) study was also done to correlate the results obtained. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
