Formation of Medical-Purpose Layered CeO2–TiNbTaZr Composite Materials by Magnetron Sputtering
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.
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.
