Abstract

The structure, morphology, and hardness of the CeO₂ surface layer formed on a Ti–29Nb–13Ta–4.6Zr alloy plate by magnetron sputtering at different process parameters are studied. Under the chosen conditions, a CeO₂ layer having the stoichiometric composition (with the fluorite-type structure, space group Fm\(\bar {3}\)m) is found to form. We detected a linear dependence of the surface layer thickness on the sputtering time and an extreme (with a maximum) power dependence of the thickness. As the thickness increases, the decrease in the hardness of the CeO₂ layer is noted. At low coating thicknesses (to 720 nm), the formation of a TiO₂ sublayer is observed.

磁控溅射制备医用层状CeO2-TiNbTaZr复合材料

研究了不同工艺参数下磁控溅射在Ti-29Nb-13Ta-4.6Zr合金板上形成的CeO2表面层的组织、形貌和硬度。在选定的条件下，发现形成具有化学计量组成（具有萤石型结构，空间群Fm \(\bar {3}\) m）的CeO2层。我们检测到表面层厚度与溅射时间呈线性关系，厚度与功率呈极端（最大）关系。随着厚度的增加，CeO2层的硬度降低。在低涂层厚度（至720 nm）下，观察到TiO2亚层的形成。

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.
