CORROSION BEHAVIOUR OF EUTECTIC ALUMINIUM CENOSPHERE COMPOSITES
Keywords:
Al-Si Eutectic Alloy, Immersion Corrosion , CensopheresAbstract
Fly ash is a particulate waste material formed as a result of coal combustion in power plants. The use of fly ash as a filler or reinforcement for aluminum alloys is therefore, very desirable from an environmental standpoint. In light of the above, the paper summarizes the development of 12% Silicon eutectic aluminium composites by stir casting route and analyzes the corrosion behaviour of the composite to sea water for a period of 35 days. Based on varied percentages of cenospheres used six compositions of the composite are prepared and evaluated for corrosive properties and hardness.
