Abstract (en)

The method of titanium surface modification by plasma electrochemical oxidation in Ca(H<sub>2</sub>PO<sub>2</sub>)<sub>2</sub> baths at a concentration from 0.01 mol·dm<sup>-3</sup> to 5 mol·dm<sup>-3</sup> with an anodic current density from 1 mA·cm<sup>-2</sup> to 250 mA·cm<sup>-2</sup> and applied voltage from 50 V to 600 V is characterized by immersing the surface-modified element in an aqueous salt solution with insoluble particles of silver(I) oxide Ag<sub>2</sub>O, copper(I) oxide Cu<sub>2</sub>O or copper(II) oxide CuO at a concentration from 1 g·dm<sup>-3</sup> to 400 g·dm<sup>-3</sup>.
