Abstract—The surface quality, structure, phase and elemental compositions, and tribotechnical characteristics of ≈1 μm-thick Ti–InSn–Cu and Ti–Pb–InSn–Cu coatings deposited by reactive magnetron sputtering under various conditions with clockwise and counterclockwise substrate rotation are investigated. In all cases, coatings with nanocrystalline structure are deposited. The morphology of the Ti–InSn–Cu coatings is discontinuous columnar, and that of the Ti–Pb–InSn–Cu coatings is layered columnar. The addition of lead is found to increase the surface roughness and the coating thickness. The microhardness of the coatings is 239–275 HV depending on composition, deposition conditions, and substrate rotation direction. The microhardness of the coatings deposited under counterclockwise rotation, where layers are deposited in the sequence TiN–Cu–InSn, is higher by 8–15%. The friction coefficient for the TiN–Cu–InSn coatings is lower than that of the Ti–Pb–InSn–Cu coatings, μ = 0.20–0.23 and ≈0.3, respectively. The substrate rotation direction during deposition influences the tribotechnical properties of the coatings.

TiN-Cu-InSn和TiN-Cu-InSn - pb多组分固体润滑剂涂料

摘要：研究了反应磁控溅射制备的≈1 μm厚的Ti-InSn-Cu和Ti-Pb-InSn-Cu涂层在顺时针和逆时针旋转条件下的表面质量、结构、相和元素组成以及摩擦技术特性。在所有情况下，都沉积了具有纳米晶结构的涂层。Ti-InSn-Cu涂层的形貌为不连续柱状，而Ti-Pb-InSn-Cu涂层的形貌为层状柱状。发现铅的加入增加了表面粗糙度和涂层厚度。涂层的显微硬度为239-275 HV，这取决于成分、沉积条件和基底旋转方向。以TiN-Cu-InSn顺序进行逆时针旋转沉积的镀层显微硬度提高了8-15%。TiN-Cu-InSn涂层的摩擦系数低于Ti-Pb-InSn-Cu涂层，分别为μ = 0.20 ~ 0.23和≈0.3。沉积过程中基材的旋转方向影响涂层的摩擦性能。

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.
