“…Theoretical model predictions are in good agreement with the experimental data (percentage of error is below 6 %, see the Table 3). From the EIS analysis it is clear that, as the potential increases, the passive oxide layer on the film becomes more porous and resistance to charge transfer decreases at the corrosion interface [18][19][20]. It is also clear that the best and worst corrosion behavior correspond to samples polarized at pitting potential -0.5 V and +0.5 V.…”

These decorative coatings require, not only an attractive appearance for market applications, but also an ability to protect the surface underneath. Because of this, corrosion, wear and their combined effects (termed tribo-corrosion) are particularly important for lifetime prediction.The tribo-corrosion behaviour of a range of single layered titanium oxycarbide, TiC x O y ,coatings, produced by DC reactive magnetron sputtering, has been studied and reported as a function of electrode potential (-0.9 V, -0.5 V, 0.0 V and +0.5 V) and applied load (3, 6 and 9 N). The study was conducted in a reciprocating sliding tribosystem (Plint TE 67/E) in a bio fluid (an artificial perspiration solution) at room temperature. During the wear tests, both the open-circuit potential and the corrosion current were monitored. 2The results showed that electrode potential and load have a significant influence on the total material loss. The variations in R p (polarization resistance) and C f (capacitance) before and after sliding, obtained by Electrochemical Impedance Spectroscopy (EIS)were evaluated in order to provide an understanding of the resistance of the film in such conditions. Tribo-corrosion maps were generated, based on the results, indicating the change in mechanisms of the tribological and corrosion parameters for such coatings.

“…The influence of contaminants and surface treatments of titanium implants (alumina-blasting, acid etching, anodization, hydroxyapatite coating, for example) on osseous integration has been extensively studied. Many works have been also published on the corrosion behavior of commercially pure titanium in artificial saliva, Ringer, Hanks solutions and others [2][3][4][5][6] . All the authors agree that the titanium corrosion resistance in these media is due to the formation of an adherent and highly protective oxide film on its surface which is mainly formed of TiO 2 [7] .…”

The electrochemical behavior of three titanium dental implants purchased on the Brazilian market was evaluated in artificial saliva using open-circuit potential measurements, electrochemical impedance spectroscopy and potentiodynamic polarization. The three implants are passive in this medium but their corrosion resistance and the stability of their passive oxide films are quite different. Although the three implants were made of commercially pure grade titanium, their corrosion current densities and passive current densities were shown to differ from one to two orders of magnitude

“…Finally, a series of potentiostatic tests (PS) at E corr were conducted to monitor evolution of current. Electrochemical impendence spectroscopy (EIS) was conducted before and after sliding to examine the changes in corrosion kinetics under mechanical stimulation [3,45]. For the investigation of tribocorrosion behavior of Ti-V …”

Orthopedic and dental implants experience the synergistic effect of wear and corrosion, i.e., tribocorrosion, which has been a major contributor to the premature failure of implants. This work focuses on the development of a compact and cost-effective tribocorrosion apparatus for the investigation of fretting and wear. The custom-built apparatus is validated with an analysis of the tribocorrosion behavior of Ti6Al-4V disks in artificial saliva (pH = 6.5, T = 37°C). Electrochemical impedance spectroscopy, potentiodynamic, free potential, and potentiostatic analyses were used for electrochemical characterization of Ti-6Al-4V disks. White light interferometry and scanning electron microscopy were used to analyze wear scars on the Ti-6Al-4V disks. Total wear loss was calculated to be 12.4 ± 1.5 lg, and the synergistic weight loss ratio (0.78 ± 0.1) showed that Ti-6Al-4V disks experience synergy of wear and corrosion, with wear being the dominant component.
