Abstract—Due to the lower-cost processing of titanium, its application in the engines as light weight material has renewed its interest in the tribological behavior. A pin on disk sliding friction test was conducted on the titanium alloy (Ti-6Al-4V). Alloy disks were slid against the bearing ball composed of stainless steels at the speeds of 0.2 and 0.8 m/s. When the sliding speed is higher the coefficient of friction and wear rate are lower. For steel the wear rate is the least. Microstructural study confirms that Ti alloys have the tendency to transfer material to their counter face and there are possible tribological reactions. Degradation of mechanical properties of contact areas of reaction products takes place

Index Terms—Titanium, Material transfer and tribological reaction
