Abstract
The method of electron beam deposition on titanium substrates was used to produce multiphase nanosized calcium phosphate materials with Ca/P atomic ratio lower than the stoichiometric one. The influence of substrate temperature on the elemental and phase composition of calcium-phosphate materials is considered. It is shown that the structure of the components of such materials can be controlled by technological means, using deposition temperature. Calcium titanates, forming during deposition, are promising for designing multilayer composite materials or prosthesis products. Results of studying resorption of calcium-phosphate materials in biological and model solutions with different pH are presented. On the whole, the formed calcium-phosphate materials belong to bioresorbable ones, and they can be used to improve the biocompatibility with bone tissue. 13 Ref., 2 Tables, 6 Figures.
Keywords: EB PVD, structure, bioresorption, calcium-phosphate materials, calcium triphosphate, titanium
