Statistical Analysis of Tribological Performance of Functionally Graded Copper Composite Using DOE

Dry sliding performance of Cu-11Ni-4Si/10wt.%Al2O3 graded composite was investigated statistically and experimentally using pin-on-disc wear tester. Microstructural analysis revealed maximum gradient concentration ceramics towards the inner radial wall developed composite. The based on Taguchi’s L27 orthogonal array Regression models, at tribo-parameters (load-15, 25, 35 N, slide velocity-1.5, 2.5, 3.5 m/s distance-750, 1500, 1250 m). Wear raised with proportional rise in load distance. Trend influential factors against response studied Analysis Variance. influence process conditions their interactions are also detailed. Worn surface identified formation Mechanically Mixed Layers intermediate velocity. This had a major over improvement resistance. is suggestable for diverse automobile components various tribology applications.
