Abstract: The purpose of this investigation is to study the effect of contact between tool and composite on wear rate of the tool shoulder in friction stir welding process. Wear rate was investigated from a weight loss of the tool shoulder after the welding process for each composites. Elevated temperature was measured to reveal the relationship between temperature and wear phenomenon. Visual and microstructure studies are utilized to observe the topography in the each tool surface wear phenomenon. FSW process was done at 1080 RPM rotational speed with translational velocity of 5.652 cm sec–1 produces a low wear rate that has good wear resistance. The elevated temperature showed 269.9°C at 5 wt.% SiC, 212°C at 7.5 wt.% SiC and 258.3°C at 10 wt.% SiC, at 1080 RPM rotational speed with the translational speed 5.652 cm sec–1 on advancing side. Higher elevated temperature decreases the wear rate. This study explains that butt joint process produced high temperature at advancing side than retreating side in each SiC particle composition. Visual and microstructure study mention that at operating speed of 1080 RPM fewer adhesive layer is found and the measurement for the thickness shows value of 0.2331 mm.
