Abstract
In present studies, the frictional and wear behavior of Al-2Mg-11TiO2 composites prepared through spray forming and stir casting techniques are studied. For the comparative purpose, the spray formed base alloy (Al-2Mg) is also tested under same sliding condition. The paper documents our findings on various wear characteristics of both composites and base alloy tested under the same range of sliding distance at various normal loads. The wear rate of spray formed composites is significantly lower than the base alloy and stir cast composite under same sliding condition. Further, a change in wear mechanism from consistently adhesive type in alloy to a mixed mode of oxidative-abrasive wear in composites is noted. A decrease in coefficient of friction in composites vis-Ã -vis matrix alloy is also observed.
