Biomimetic apatite coatings on micro-arc oxidized titania.
TL;DR: The use of 1.5 SBF shortened the apatite induction time andApatite formation was confirmed even on the surface of the films oxidized at 350 V, which suggests that the incorporated Ca and P in the titania films play a similar role to the Ca- and P-containing compounds in the SBF.

A comparison of corrosion, tribocorrosion and electrochemical impedance properties of pure Ti and Ti6Al4V alloy treated by micro-arc oxidation process
TL;DR: In this article, the micro-arc oxidation (MAO) coatings were performed on pure Ti and Ti6Al4V samples at 180 V. According to polarization curves, the corrosion resistance of untreated samples was significantly increased by MAO process, which indicates that corrosive ions diffusion throughout the oxide film would be more difficult resulted in a higher corrosion resistance.
