Abstract:
The reinforcement of Al₂O₃ in aluminum metal matrix composites is very popular these days because of their large number of applications. Al- Al₂O₃ composites covers a lot of sectors like automotive, aerospace, aeronautical and defense due to their low weight & excellent mechanical properties like strength, hardness etc. In the current study, Al- Al₂O₃ composites have been produced by adding a different amount of V₂O₅ particles in Al-Si alloy. The influence of V₂O₅ addition on wear has investigated. The influence of sliding distance, amount of V₂O₅ addition and sliding velocity effect on wear behavior have been analyzed experimentally and discussed. An improvement in wear behavior has been observed in developed composite as compare with base alloy. The development of hard Al₂O₃ particles within the melt increases the composite hardness which in turn improves the wear behavior. The coefficient of friction of cast in-situ Al- Al₂O₃ composites was determined at different loads by tribotester. The research revealed that the coefficient of friction and wear loss increases with the load.
