Ti185 alloy is widely used in key industrial fields such as aerospace due to its excellent mechanical properties. The traditional method of preparing Ti185 alloy will inevitably appear “β fleck”, resulting in the decrease of mechanical properties, and the high price of V element limits the wide application of Ti185. In this paper, a low-cost master alloy V-Fe powder is used, a dense block is prepared by spark plasma sintering (SPS) technology, and a high-performance Ti185 alloy is prepared by controlling the sintering parameters. XRD and SEM were used to investigate the phase and microstructure of the samples prepared under different parameters. The compressive strength and friction properties of the directly prepared samples were studied. The samples with a sintering temperature of 1350 °C and a holding time of 30 min exhibited the most excellent comprehensive performance, with the highest compressive strength and lowest friction coefficient of 1931.59 MPa and 0.47, respectively.
