Assessment Of Wear Resistance And Hardness Of Za 27, Al7075, Hypoeutectic And Hypereutectic Al-Si Alloys
Within the last few years there has been a fast increase in the development of Aluminium and its alloys,
particularly in the automobile and aerospace industries, due to their high strength to weight ratio, high wear resistance, low
density and low coefficient of thermal expansion. The advancements in the field of application make the study of their wear
resistance and hardness an utmost importance. This paper attempts to assess the wear resistance of Al 7075, ZA 27,
Hypoeutectic and Hypereutectic Al-Si alloys using Pin–on–disk wear system as per ASTM G 99 and also hardness of these
alloys using Brinell’s hardness tester. The results obtained shows that Al 7075 possesses greater wear resistance and
