Article

Results are presented of studies of the physical-mechanical properties of silver-doped calcium phosphate coatings formed by radio-frequency magnetron sputtering on a surface of technically pure VT1-0 titanium and 12Cr18Ni10Ti stainless chromium‒nickel surgical steel. The films have the nanocrystalline structure of hydroxyapatite with mean diameter of the coherently diffracting domains equal to 20–30 nm. It has been established that the configuration of the magnetic field of the magnetron has an effect on the roughness, thickness, and refractive index of the coatings. The thickness of the coatings and the refractive index vary within the ranges 300–700 nm and 1.68–1.80, respectively. The nanohardness of the coatings is within the range 4–7GPa, the modulus of elasticity of the coatings depends on the material of the substrate and is equal to 130–150 GPa for titanium and 170–200 GPa for steel. Sclerometric measurements of the coatings made it possible to establish a high adhesion strength of the coatings.
