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.

Ti185合金由于其优异的机械性能而广泛用于航空航天等关键工业领域。传统的制备Ti185合金的方法不可避免地会出现“ β斑点”，导致机械性能下降，而V元素的高价限制了Ti185的广泛应用。本文使用低成本的中间合金V-Fe粉末，通过火花等离子体烧结（SPS）技术制备致密块，并通过控制烧结参数制备高性能的Ti185合金。用XRD和SEM研究了在不同参数下制备的样品的相和微观结构。研究了直接制备的样品的抗压强度和摩擦性能。烧结温度为1350°C，保温时间为30分钟的样品表现出最优异的综合性能，其最高抗压强度和最低摩擦系数分别为1931.59 MPa和0.47。
