Titanium and its alloys have poor wear resistance. To improve their wear resistance, ceramic-particulate reinforced titanium matrix composites (TMCs) were fabricated by spark plasma sintering process (SPS). The influencing factors on wear resistance about TMCs in Taguchi Method are classified by the noise factors as load, sliding velocity, sliding distance, counterpart material, temperature, humidity, and the control factors as matrix material, shape of matrix, particle size of matrix, reinforcement material, and reinforcement volume fraction. In this study, the control factors were selected to optimize in them by the method. The experiments were conducted systematically based on L18 orthogonal array of the method. Wear tests were carried out using a three-ball-on-disk machine. The results indicated that the wear resistance of TMCs was affected by three factors, such as matrix material, reinforcement material, and reinforcement volume fraction. The Si3N4 reinforced hydride-dehydride Ti matrix composite with 10vol. % reinforcement showed good wear resistance.
