Abstract

In the present experimental investigation AA6082/Si3N4/C/Al2O3 composite was successfully fabri-cated using stir casting technique combined with electromagnetic stirrer for wear resistance applica-tions. The produced AA6082/Si3N4/C/Al2O3 composite exhibits improved tribological and me-chanical and properties, according to the experimental results. The generated composite has a micro-hardness range of 60 to 110 HV and an average UTS of 150 to 200 MPa. The tribological perfor-mance was evaluated using a pin on disc tribometer. The tribometer yields a COF reading be-tween 0.15 and 0.4 for test circumstances of load between 10N and 30N, temperature between 50oC and 100oC, and sliding velocity between 0.1 m/s and 0.3 m/s, respectively. Taguchi L9 OA was also used in the present investigation for optimization of COF of fabricated AA6082/Si3N4/C/Al2O3 compo-site. The percentage contribution of fabricated composite for COF was highest for velocity (76.37%) followed by 12.84 % temperature and 7.31 % load. The following are the predicted ideal values for the 95% confidence interval for COF for the fabricated AA6082/Si3N4/C/Al2O3 composite. 0.86 µ < 0.134 for CICE and CIPOP: µ < 0.0126 < 0.094

Keywords: AA6082/Si3N4/C/Al2O3 composite; SEM-EDAX; COF; Taguchi.
