| Popis: | In present research work, aluminum-based hybrid metal matrix composites (HMMCs) reinforced with Al2O3 and SiC particles were fabricated by stir casting method. A total of three hybrid composites (Al + SiC (1.5%) +Al2O3 (1.5%), Al + SiC (3%) +Al2O3 (3%), Al + SiC (4.5%) +Al2O3 (4.5%)) were made and parametric study (applied load, rpm, and time) was carried out on wear behavior of composites. Objective of the model was chosen as ‘smaller the better’ characteristics to analyze the wear resistance. Test on the samples was carried out as per the ASTM standards. ANOVA with L9 orthogonal array was selected to analyze the experimental data using Taguchi method. The specific wear resistance and hardness were improved significantly by adding reinforcement. According to the design expert with variable parameter, the best desirability results were found for Al + SiC (4.5%) +Al2O3 (4.5%) having maximum S/N ratio and minimum specific wear rate. The S/N ratio was found maximum with Al + SiC (4.5%) +Al2O3 (4.5%) and minimum with Al + SiC (1.5%) +Al2O3 (1.5%) among all composites. |
