Influence of heat treatment on corrosion rate of aluminium A356 reinforced with mica and titanium di oxide

Abstract

Composite material plays important role in the field of engineering and has vast applications in the aerospace, marine industries, automobiles, recreational etc. Researchers are always engaged in identifying the hidden parameters of the composites. In this present study, aluminium A356 alloy is proportionally mixed with the reinforcements like titanium di oxide (TiO2) and mica by using vortex method. The matrix A356 is mixed with equal proportions of TiO2 and mica (1 wt%, 2 wt%, 3 wt%, 4 wt% and 5 wt%) and different castings formed are subjected to various heat treatment process. Once the different ageing conditions are achieved, the specimens are studied for the corrosion behavior. Results suggest that the specimen with double ageing (4 h) is having greater resistance to corrosion. The density of the prepared casting decreased with increase in reinforcement.
