In the present investigation, Aluminium based particulate composites
containing 15 weight percentages of two types of flyash particulates as
reinforcement were synthesized using stir-casting method and their
properties are compared. The properties like density, sliding wear,
hardness, slurry erosive wear and corrosion resistance of the composites
were investigated and their properties are compared. The results of wear
studies have shown that the resistance to wear increases with the
inclusion of flyash as compared to base metal. The addition of flyash
particles reduces the density of composite while increasing the hardness.
Corrosion resistance decreases with increase in flyash content. The
macrostructural and microstructural characteristics of the MMC were
investigated with particular emphasis on the distribution of flyash particles
in the matrix.
