Friction and wear behaviour of new generation Ultra-High Molecular Weight Polyethylene (UHMWPE), Highly Cross-Linked UHMPE (HXLPE) and Vitaminized E XLPE (VE-XLPE), sliding against TiAl6V4 alloy under dry and lubricated conditions were investigated. Tribological tests were conducted by using a reciprocating pin-on-flat tribometer under hip replacement implants conditions. Lubricated sliding tests were carried out with a biological fluid that approximates well the synovial fluid present in the joints with imposed boundary mechanism. The worn samples of the HXLPE and VE-XLPE were analyzed with a gravimetric weighing scale with a sensitivity of 0,1 mg. The evolution of the friction coefficient of the HXLPE/Ti6Al4V and VEXLPE/Ti6Al4V pairs were also compared.
