PEEK (poly-ether-ether-ketone) is a semi crystalline thermoplastic with excellent mechanical and chemical resistance properties. In this work the influence of TiO2 nanoparticle at various concentration (0.5, 1 and 1.5 wt. %) on tribological and mechanical properties of PEEK were investigated. The mechanical properties of PEEK Nano composites were studying to evaluate the influence of the nanoparticles addition, as well as examining the relation between the tribological and mechanical behavior. In addition, the erosion rate examined by using erosion test Rig. the conditions of test are: Grains of sand (450 μm) as an erodent at different time every half hour period (0.5 to 2.5) hour, at 90° impingement angle at room temperature. The improvement in mechanical properties can improve the wear resistance. the maximum improving was obtained in addition 0.5wt. % TiO2 Nano-particles. Tribological properties include erosion resistance were increasing with addition of TiO2 Nano particles compared with pure PEEK. PEEK and PEEK /TiO2 composites have a good UV resistance within the 300h period.
