In-vitro dissolution and structural and electrokinetic characteristics of titanium-oxynitride coatings formed via reactive magnetron sputtering

The results of investigation into the structure and in-vitro dissolution of titanium-oxynitride coatings deposited via reactive magnetron sputtering are presented. Data on the electrostatic and ζ surface potentials enable estimation of their contribution to adsorption processes and coating dissolution in vitro. Sample cultivation in a solution simulating the composition of the inorganic part of human blood plasma leads to surface mineralization, reduces the value and sign of the surface potential, and alters the surface wettability. The coating prevents the transition of iron ions into a solution and does not induce the calcification of an artificial surface.
