Abstract

Metal matrix composite of aluminium was developed because of excellent properties like high level of strength, light weight, stiffness, and wear resistance. An effort is made to investigate the impact of reinforcement particles namely aluminium nitride on Tribological behaviour of aluminium 7075 alloy matrices. The percentage weight of aluminium nitride particulate considered here is 2wt% to 10wt% in a step of 2wt%. Stir casting process liquid metallurgy method is used to manufacture of composites. The as-cast aluminium alloy and composites specimens are prepared by lathe machine and prepared for heat treatment by subjecting to a temperature of 470ºC for 2-hour solutionizing treatment followed by ice medium quenching, next the specimens are subjecting to artificial ageing for duration of 8 hour with temperature of 120°C. Through a pin and disc test machine, the Tribological characteristics of as cast and composite alloys were investigated both before and after heat treatment. The wear rate was examined as a function of sliding velocity and applied load. Using a scanning electron microscope, the wear surface morphology and pin wear behavior were examined.
