Abstract

Abstract: Aluminum matrix composites (AMCs) are extensively using in different fields such as defense automotive, marine, electronics and automobile sectors because of their impressive mechanical properties. This study aims to investigate the tribological and corrosion behavior of AA6061 alloy with the reinforcement of ilmenite (FeTiO3 ) particles. AA 6061-(FeTiO3 ) composites were fabricated througha stir casting process with AA 6061 as matrix material and ilmenite (FeTiO3 ) particles in different wt.% (5%, 10% and 15%) as reinforcement. In this investigation, the composites' properties like hardness, wear behavior, coefficient of friction and pitting corrosion behaviour were evaluated. From these tests, it is noticedthat hardness increased and wear rateand coefficient of friction decreased with the addition of ilmenite as reinforcement in AA6061 alloy. Pitting corrosion resistance of composites with 10%ilmenite is better than remaining composites and base metal.
