Abstract

Anticorrosive bioactive coatings with synthetic nanosized hydroxyapatite prepared on magnesium. A.B. PODGORBUNSKY, I.M. IMSHINETSKIY, D.V. MASHTALYAR, A.S. GNEDENKOV, S.L. SINEBRUKHOV, S.V. GNEDENKOV (Institute of Chemistry, FEB RAS, Vladivostok).

The results of the optimization of the method for obtaining calcium-phosphate compounds (hydroxyapatite) and the formation of bioactive coatings based on it are presented. The coatings obtained by the methods of plasma electrolytic oxidation and spin-coating are positioned as bioresorbable and are used as anticorrosive, providing first of all the controlled dissolution of a metal (magnesium) implant in the body’s environment. Various types of magnesiumbased materials were used as a substrate for the formed protective layers: pure magnesium with different porosities; magnesium-hydroxyapatite composites; magnesium alloy МА8. The morphology, phase and elemental composition of the formed layers and magnesium composites have been investigated. A comparative analysis of the physicochemical properties of the obtained coatings indicates a significant improvement in the protective characteristics and a slowdown in the corrosion destruction of a substrate material.
