Bioactive coatings of porous materials: Fabrication and properties

详细

The methods for producing implants based on a metal matrix with a bioactive coating are described. Porous titanium and titanium nickelide obtained by ion-plasma sputtering are selected as the metal substrate. The bioactive coating is formed from an aqueous suspension of hydroxyapatite. Various methods of deposition are proposed such as vacuum impregnation, its combination with centrifugation, and exposure to ultrasound. Their comparative estimation is given. The surface morphology of the samples is studied by electron microscopy; the characteristics of the surface are estimated by the Brunauer−Emmett−Teller method.
