Effect of TiO₂ inoculants on the wear conduct of the aluminium AA 6061/red mud high performance hybrid composite

The current work focuses on the manufacturing of aluminium AA 6061 composites and its tribological characterization. This is achieved by reinforcing matrix with red mud. However, uniform dispersion mud requires ultrasonic assisted stir casting use optimum wt.% TiO 2 inoculants. In this regard, composition fixed at wt.%, since addition beyond results in agglomeration, while inoculants varied from to 6 wt.%. wear tests are conducted as per L9- Orthogonal Array (OA) for a load range 10 N 30 N, sliding distance 500 m 2500 m, disk rotation speed 200 RPM 600 RPM. regression coefficients more than 0.9 close unity error between experimental outcomes statistical values within tolerance band. SWR COF minimized mud, 4 , which there slight increase attributed agglomeration reinforcments certain localized regions presence voids other regions.
