Samples of aluminum-silicon eutectic alloys were cast via stir casting method to investigate their wear behavior. Three types of samples were prepared. The first solidified under the effect of mechanical vibration (using an amplitude of 0.5 mm and a frequency of 25 Hz); the second has an addition of 0.13 wt% titanium as alloying element; while the third cast with the combined effect of added titanium and mold vibration. Chemical composition test, scanning electron microscope (SEM) analysis, macro-hardness and wear tests were done for the prepared samples. The results showed that at 27 ºC for 25 minute loading with a load of 20 N, the lowest wear rate of sample prepared with the combined effect of mold vibration and addition of titanium, the biggest wear rate for sample with the effect of vibration, and the wear rate of sample prepared with addition of titanium between them. The wear rate at 100 ºC is lesser than that at 27 ºC for all samples at the same conditions.
