Abstract
Porous bioactive membrane-type calcium phosphate coatings on metal substrates are produced. Their microstructure and physicochemical properties are studied. Titanium (including porous) and medical stainless steel are used as metal substrates. The bioactive coatings are based on biogenic hydroxyapatite or synthetic calcium phosphates (calcium phosphate content was between 68 and 85 %) and sodium borosilicate glass. To add bacteriostatic properties to the coatings, some compositions were additionally doped with cerium dioxide (5 %). The surface microstructure, some mechanical properties, and in vitro behavior of the coatings in physiological solution are examined.
