Abstract—

The paper presents the results of a study on how the addition of titanium powder affects the tribotechnical properties of a copper-based powdered friction material when operating under friction boundary conditions. It is shown that the introduction of 5–25 vol % titanium powder increases the friction coefficient from 0.054 to 0.096. This is due to the formation of a layer of carbide, carbon nitride, and titanium nitride on the surface of a titanium particle during sintering of the friction material, as well as an intermetallic compound of the titanium-copper system up to 6 μm thick with a microhardness of 4000–3000 MPa. The data obtained made it possible to develop a friction material that increases the service life of oil-cooled brakes.

添加钛粉的铜基粉末摩擦材料的摩擦学性能

摘要—

本文介绍了在摩擦边界条件下工作时，钛粉的添加如何影响铜基粉状摩擦材料的摩擦学性能的研究结果。结果表明，引入5-25％（体积）的钛粉会使摩擦系数从0.054增加到0.096。这是由于在摩擦材料的烧结过程中，钛颗粒表面形成了一层碳化物，氮化碳和氮化钛，以及厚度达6μm的钛铜系统的金属间化合物。显微硬度为4000-3000 MPa。所获得的数据使得开发一种摩擦材料成为可能，该材料可以延长油冷制动器的使用寿命。
