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 behavior in Taguchi Method are classified by the noise factors as load, sliding velocity, sliding distance, and the control factors as type, shape, particle size of matrix material, type of reinforcement material, and reinforcement volume fraction. In this study, the control factors were selected to optimize them by the method. The experiments were conducted 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 behavior of TMCs was affected by three factors, such as type of matrix and reinforcement material, and reinforcement volume fraction. The Si3N4 reinforced hydride-dehydride Ti matrix composite with 10 vol.% reinforcement showed good wear resistance.
