“…4a, b. In both groups of samples, R and A TiO 2 phases were identified, as already registered in others similar studies [16,61,73]. After the analyzes of the X-ray diffractograms, a different relative proportion of the polymorphs of TiO 2 between PEO_CE,8,10 and PEO_Cβ,25,10 samples was found.…”

“…1b-e. After anodic oxidation treatments, the surfaces presented porous structures, which are typical to obtain after PEO treatments [67]. Micropores are produced in the dielectric breakdown regime associated to high local temperatures, sparks production, and the vigorous release of oxygen and/or water vapor release at surface/electrolyte interface [16,46,61].…”

“…This electrolyte was chosen once on one side, it has been generally used in previous research works [2,18,61,62,63] but also because the electrochemical behavior of metallic materials in Fusayama's saliva, its similar to the one observed in human saliva [64]. It is aimed to simulate the highly corrosive oral cavity environment with Cl − , F − , and H + ions playing a significant role on corrosion of dental implant materials [20].…”

“…Alves et al n.s. means that measurements were not significant [61] studied the tribocorrosion behavior of anodic films produced in an electrolyte containing β-glycerophosphate and different concentrations of calcium acetate. The authors hypothesized that the reason for the much better tribocorrosion behavior of samples anodized in the higher calcium acetate concentration electrolyte, was the crystalline structure (presence of anatase/rutile) and calcium content on those samples.…”

Tribocorrosion Behavior of Calcium- and Phosphorous-Enriched Titanium Oxide Films and Study of Osteoblast Interactions for Dental Implants

Titanium (Ti) dental implants are frequently exposed simultaneously to a corrosive environment and cyclic micromovements at implant/abutment and implant/ bone interfaces, becoming part of a tribocorrosion system. Thus, wear debris and corrosion products/ions can be released to peri-implant tissues and induce inflammatory reactions leading to implant failure. Moreover, the poor osseointegration is also one of the main problems affecting dental implants lifetime. Surface modification strategies have been proposed to design novel Ti oxide-based multifunctional surfaces that are able to simultaneously improve cellular functions and provide enhanced tribocorrosion resistance. Hence, the main objective of this work was the synthesis of Calcium (Ca)-and Phosphorous (P)-enriched Ti oxide films aimed to display superior wear/corrosion performance and simultaneously, to enhance osteoblast-material interactions. Ca-and P-enriched films were synthesized by plasma electrolytic oxidation (PEO) and their characteristics were assessed by Field emission scanning electron microscopy, profilometry, energy-dispersive X-ray spectroscopy, X-ray diffraction, and water contact angle measurements. PEO-treated samples were subjected to pin-on-disk reciprocating sliding tests in artificial saliva at 37°C. The viability of MG63 cells cultured on PEO-treated samples was investigated by MTT assay, and their adhesion ability by SEM and confocal laser scanning microscopy. The wear/corrosion behavior of Ti was improved after PEO treatments and the electrolyte composition appeared to play a crucial role both on its corrosion tendency and mechanical wear resistance. It is believed that this improvement is related to the higher rutile/anatase ratio exhibited by Ca-and P-enriched surfaces. Osteoblasts were well spread on these surfaces displaying improved viability/proliferation compared to Ti.

“…Electrochemical techniques are well suited for the investigation of the tribocorrosion phenomenon. Different studies on tribocorrosion mechanisms of titanium alloys [25][26][27][28] observed a synergistic effect between wear and corrosion that increase metal degradation rate. Otherwise, since titanium alloys are passive materials, chemical contribution to wear rate is less than 10% and they normally present an abrasive wear and plastic deformation [29][30][31].…”

ElsevierGuiñon Pina, V.; Dalmau, A.; Amigó Borrás, V. (2015). AbstractThe tribo-electrochemical behavior of different  titanium alloys for biomedical applications sintered by powder metallurgy has been investigated. Different mechanical, electrochemical and optical techniques were used to study the influence of the chemical composition, Sn content, and the electrochemical conditions on the tribocorrosion behavior of those alloys Ti30NbxSn alloys (where "x" is the weight percentage of Sn content, 2% and 4%).Sn content increases the active and passive dissolution rate of the titanium alloys, thus increasing the mechanically activated corrosion under tribocorrosion conditions. It also increases the mechanical wear of the alloy. Prevailing electrochemical conditions between -1 and 2 V influences the wear accelerated corrosion by increasing it with the applied potential and slightly increases the mechanical wear of Ti30Nb4Sn.Wear accelerated corrosion can be predicted by existing models as a function of electrochemical and mechanical parameters of the titanium alloys.

Corrosion behavior of surface modifications on titanium dental implant. In situ bacteria monitoring by electrochemical techniques

The effects of surface modifications and bacteria on the corrosion behavior of titanium have been studied. Five surface modifications were analyzed: two acid etchings (op V, op N), acid etching + anodic oxidation (op NT), sandblasting + acid etching (SLA), and machined surfaces (mach). The corrosion behavior of the surface modifications was evaluated by following the standard ANSI/AAMI/ISO 10993-15:2000. Cyclic potentiodynamic and potentiostatic anodic polarization tests and ion release by ICP-OES after immersion for 7 days in 0.9% NaCl were carried out. Microbiologically induced corrosion (MIC) of low and high roughness (mach, op V) was assessed in situ by electrochemical techniques. Streptococcus mutans bacteria were resuspended in PBS at a concentration of 3 × 10 bacteria mL and maintained at 37°C. MIC was measured through the open circuit potential, E , and electrochemical impedance spectroscopy from 2 to 28 days. Potentiodynamic curves showed the typical passive behavior for all the surface modifications. The titanium ion release after immersion was below 3 ppb. In situ bacteria monitoring showed the decrease in E from -0.065 (SD 0.067) V in mach and -0.115 (SD 0.084) V in op V, to -0.333 (SD 0.147) V in mach and -0.263 (SD 0.005) V in op V, after 2 and 28 days, respectively. A reduction of the oxide film resistance, especially in op V (54 MΩ cm and 6 MΩ cm , after 2 and 28 days, respectively) could be seen. Streptococcus mutans negatively affected the corrosion resistance of titanium. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 106B: 997-1009, 2018.
