Abstract

The regularities of the coating formation in an alkaline electrolyte by the method of plasma electrolytic oxidation on the titanium surface previously nitrided by gas and plasma methods were investigated. It was established that such complex treatment allows formation of the hydrophilic porous hydroxyapatite coating with a thickness up to 100 m and a Ca/P ratio closer to biological hydroxyapatite.
