8.2.5 ZrO 2 films. Zirconium oxide is a bio-inert nonresorbable metal oxide that is characterized by high hardness, superior mechanical properties, excellent chemical stability, and corrosion resistance and, therefore, can be used for hard tissue replacements (Piconi and Maccauro, 1999; Ferraris et al., 2000 ).

It is well known that oxygen diffuses inwards across the oxide film while cations are relatively immobile during the oxidation of Zr . 11. Therefore, the new oxide layers form at the metal/oxide interface as the oxidation progresses. Oxygen diffusion assisted by an electric field (Mott potential) governs the early stages of metal oxidation. 12-14
