Characterization of Aluminium Hybrid Composite Reinforced with Rice Husk Ash and Molybdenum Disulfide Processed through Compo Casting

Abstract

The focus of the current study is lies on the development of high performance self lubricating aluminium composite material with low cost reinforcements. The base material selected for the composite development is Aluminium 6061 whereas the rice husk ash (RHA) and molybdenum disulfide are chosen as primary and secondary reinforcements. The fabrication methodology selected to process this novel composite is compo casting in which the amount of rice husk ash in aluminium matrix is varied from 0 to 15% with constant increment of 5% and the amount of solid lubricant is fixed as 3%. The developed composite is analyzed for its density, hardness, tensile and wear properties. The results reveals that the developed composite is lighter than the base material and it posses high hardness and tensile strength also. The wear resistance capability of the aluminium is also considerably decreases with RHA addition.
