Ti6Al4V alloy was consolidated by hybrid spark plasma sintering at a temperature of 1200oC, pressure of 50 MPa, holding time of 5 min and heating rate of 100oC/min. This resulted in the maximum value of sintered density. Microstructural evolutions of the sintered compact were analysed with SEM. Sliding wear test were accomplished at different sliding loads of 5, 8 and 10 N using ball on disc tribometer configuration with stainless steel as the counterface material. Wear debris obtained was found to contain mostly the sintered materials with minute traces of the counterface material. The coefficient of friction reaches the maximum with increase in applied load. Worn surface analyses revealed the wear mechanism was abrasive. The potentiodynamic polarisation of the sintered compact showed the sintered compact in 0.9 wt % NaCl solution exhibited more resistance to corrosion.
