Abstract Scope |
In this experimental study, quartz, barite and quartz/barite reinforced AA6063 Aluminium Alloy were produced using double stir casting method. Reinforcements were added in particulates form (5, 10, 15, 20 and 25 wt. %) to the aluminium matrix. Wear, microstructural, and mechanical characterizations were carried out. Results show that mechanical properties of the composites were enhanced by the reinforcement. The wear rate was found to decrease with increase in weight fraction of the reinforcement in all cases. Coefficient of friction of composites ranges between 0.32 – 0.56 while thermal conductivity lies between 0.082 – 0.252 W/mK. AA6063/quartz-barite composites show superior wear, mechanical and thermal properties to current used brake pad materials in utility vehicles. |
