摘要
Aluminum alloys are used frequently in aerospace and ship building industry. Due to poor wear and corrosion resistance, conventional aluminum alloys are replaced by metal matrix composites (MMC). Aluminum alloy matrix reinforced with ceramic particles (TiB2) has importance in industry where components slide each other. The main task is to produce MMCs with low cost effective way to meet the requirement. In this study, an attempt is made to produce AA6061/TiB2 MMCs with different volume fractions of ceramic particles using friction stir processing technique. The dry sliding wear behavior of composites was investigated using pin on disc method. The lowest wear resistance has obtained for 8% composite. The corrosion of composites was analyzed by salt spray method. It was found that wear and corrosion resistance was increased with increase of reinforcement which was higher for 8% composite.
