EMPIRICAL MODELLING AND OPTIMIZATION OF SLIDING WEAR BEHAVIOUR OF COPPER-GRAPHITE COMPOSITES USING RSM

摘要

Copper-Graphite composites have been prepared through powder metallurgy (P/M) method. 03 and 6 wt% of graphite particles have been added as the reinforcement to the Copper powder which forms the matrix and composites have been prepared. Microstructure of the newly prepared composites was analyzed using Scanning Electron Microscopy (SEM). Wear test was done using Pin-on-disc tribometer according to G99 standards. A linear regression Mathematical model has been developed using RSM to predict the sliding wear behavior of the composites. Optimization has been done using RSM and also based on ANOVA to find the significant parameters affecting the sliding wear.
