Wear and friction coefficient of particle reinforced Ti-alloys
Abstract
<p>Particulate Reinforced Titanium matrix composites (PRTi) exhibit some improved specific mechanical properties in comparison with those of unreinforced titanium alloys as a result of the combination of the high strength and stiffness of ceramic particles with the toughness and damage tolerance provided by the metal matrix. The poor tribological properties of the titanium exclude titanium alloys from applications where wear resistance is required (brakes, rotating parts, sliding parts). The addition of ceramic particles improves the tribological properties of metals sensitive to adhesive and /or abrasive wear significantly. In this work, the wear resistance and the friction coefficient of Ti6Al-6V-2Sn reinforced with TiC particles and Ti6Al-4V reinforced with SiC particles (prototype material) are compared with the unreinforced alloys. Pin on disc and pin on ring tests were carried out against standard steel (100Cr6) as a function of pressure, speed and temperature. The results show generally a higher friction coefficient and wear resistance for the PRTi than for the unreinforced alloys. The microstructures of the pins, discs and rings were analysed using light optical microscopy and scanning electron microscopy including EDX micro-analysis in order to conclude on the dominating wear mechanism.</p>
