Hot Isostatically Pressed (Ti-Ni) samples are prepared by subjecting them to different sintering temperatures ranging from 750 to 1150 °C. Wear tests were conducted using a ball-on-plate type Oscillating tribometer, under different applied loads of 2, 8, and 16 N respectively. The morphological characterization indicated that the mean pore, and crystallite size continuously decreases with increasing sintering temperature to reach the lowest value at 1150 °C, respectively. The relative density of the 1150 °C sintered sample is as high as 98.0 %. Moreover, the higher sintering temperatures lead to the higher relative density and the greater hardness and young modulus of the sample. Both the friction coefficient and wear rate were lower in the samples sintered at 1150 °C. This improvement in friction and wear resistance is attributed to the grain refinement and closed porosity. The Ti-Ni sintered at 1150 °C showed good tribological performance under all test conditions
