“…The EDX analysis of anodic mixed porous TiO 2 –ZrO 2 films is given in Figure c. It can be observed that the wt % corresponding to Zr element is almost double (21.04 wt %) compared to the value of untreated titanium alloy surface (10.96 wt %), as presented in Table . This can be explained by the fact that the standard reduction potential of Zr → Zr 4+ is 1.553 V, ,, lower than that of Ti → Ti 4+ , which is 2.132 V. , The effect of standard reduction potential value is a much more rapid oxidation of Zr element than Ti element, according to the following reactions The process of oxidation of zirconium and the formation of zirconium oxide faster than those for TiO 2 can also be supported by the standard enthalpy value of its formation, which is −264.199 gram calories per mole for ZrO 2 , whereas that for TiO 2 is −228.360 gram calories per mole. ,, …”

“…The anode and cathode were maintained at a constant distance of 30 mm. The growth of mixed porous TiO 2 –ZrO 2 thin layer was obtained by applying a voltage of 200 V for 2 min. , During the anodic oxidation process, the electrolyte was stirred at 300 rpm to accelerate the escape of gas from the surface of the anodic electrode and keep the homogeneity of the electrolyte. After anodic oxidation, the specimens were washed carefully with distilled water in an ultrasonic bath for 10 min and finally dried in air. , …”

A thin porous mixed layer of TiO2–ZrO2 was grown on titanium–zirconium alloy surface by electrochemical oxidation. Further comparison of the corrosion behavior in Fusayama–Meyer biological solution was performed. Scanning electron microscopy surface morphology investigations confirm the presence of porous oxide film, while energy-dispersive X-ray spectroscopy analyses provide a high amount of oxygen element in the porous film and a higher amount of Zr element, concluding the mixed nature of oxide film formed, TiO2–ZrO2. For corrosion investigations, electrochemical techniques such as open-circuit potential, electrochemical impedance spectroscopy, and potentiodynamic polarization were applied. The corrosion investigations reveal better behavior of the thin porous mixed oxide layer on titanium alloy compared to the untreated alloy having on their surface the native oxide formed in contact with the air, confirming the possibility to improve the properties of such implant application in saliva solution.

Oral rehabilitation devices are susceptible to bio-tribocorrosion phenomena in the oral environment due to the synergism of wear, chemical, biochemical, and microbiological processes. This review summarizes the clinical problems and advances obtained based on current scientific evidence as well as the influence of tribological fundamentals, testing methodologies, and protocols in tribocorrosion analyses. The main clinical question related to oral rehabilitation with dental implants is the treatment failure, which is influenced by material degradation. Titanium-based implants are exposed to wear and corrosion challenges in the oral environment since the implantation and along the lifetime service. The titanium (Ti) properties such as structural material, connection design, surface treatments, alloying elements are influencing factors for material behavior. In addition, wear-corrosion factors such as cyclic loads, micromovements, oral biofilm, decontamination methods are also associated with dental implants degradation. These environmental conditions to which dental implants are submitted leads to the release of Ti particles and ions with cytotoxic and harmful effects on peri-implant surrounding tissues. In this context, the current state of the art of bio-tribocorrosion over the last decade has been steadily increasing to understand material degradation. The basic test system used to translate the tribocorrosion phenomena in the oral environment to the bench consists of electrochemical and tribological synergic analysis. The mechanical (applied load, frequency, stroke distance, and number of cycles) and electrochemical (solution composition, concentration of anions, and pH) test conditions are determinants for materials tribocorrosion performance. To overcome the tribocorrosion phenomena some strategies have been used such as alloying elements for Ti-alloys manufacture, surface treatments, and biomolecules immobilization. Further studies need to have the tribocorrosion analyses as the basis for new smart materials development considering the importance of such aspects for the biomaterial clinical behavior. Finally, tribological tests are relevant strategies for understanding the mechanisms of degradation in the oral environment and for providing a way to improve the clinical outcomes of dental implants.
