Abstract—The structure and tribotechnical properties of composite materials (CMs) based on the Sn–Sb–Cu system and reinforced with 3 wt % TiNi have been investigated. A RotoTec LT 29240 powder and a B83 alloy of similar chemical composition are used as a matrix material. A technology for manufacturing the CMs is proposed. The addition of 3 wt % TiNi is shown to increase the hardness of the CMs by 12%, to decrease the mass wear rate by 15%, and to stabilize friction when the axial load increases from 0.5 to 2.5 MPa. The proposed conditions can be used to manufacture a B83-alloy-based CM with a more stable coefficient of friction.

确保稳定摩擦过程的Sn-Sb-Cu-TiNi复合材料

摘要：研究了3wt % TiNi增强的Sn-Sb-Cu复合材料（CMs）的结构和摩擦技术性能。采用RotoTec LT 29240粉末和化学成分相似的B83合金作为基体材料。提出了一种制造CMs的技术。当轴向载荷从0.5 MPa增加到2.5 MPa时，添加3 wt %的TiNi可使cm的硬度提高12%，质量磨损率降低15%，并能稳定摩擦。所提出的条件可用于制造具有更稳定摩擦系数的b83合金基复合材料。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
