Abstract
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.
Highlights
Aluminum Alloys are widely used in industrial applications automotive, aerospace and ship building area due to high strength to weight ratio and better corrosion resistance but they exhibit inferior tribological properties [1]

Summary
Aluminum Alloys are widely used in industrial applications automotive, aerospace and ship building area due to high strength to weight ratio and better corrosion resistance but they exhibit inferior tribological properties [1]. The Friction stir processing (FSP) is modification of FSW [12] techniques which refines the microstructure, improves the mechanical properties and be used for production of composite in solid state itself Further this process produces a homogeneous distribution of reinforcement particles in the aluminum matrix [13]. FSP was emerged as novel technique to fabricate metal composites and is based on the FSW In this process, the aluminum alloys metal matrix composites in the solid state itself. Mandal et al [20] studied dry sliding behavior of TiB2 composites produced by in situ method They reported that wear resistance was improved with increase of TiB2. An attempt was made to study the wear and corrosion properties of the AA 6061/TiB2 composite made by FSP route
