“…After sliding, average R S , R P , and CPE are calculated to be 269.1 ± 6.9 X, 1.2 ± 0.11 9 10 7 X, and 2.6 ± 0.4 9 10 -5 Fs , respectively. These values are similar to those reported in literature [43,44]. However, Mathew et al reported R P values to be much lower [43].…”

“…Compared to corrosiononly PD scan, the E corr of Ti-V alloy during tribocorrosion is slightly higher (-0.8 vs. -0.6 V. Upon initiation of sliding, the current increased drastically (cathodic shift) and reached a fluctuating range of 1 and 100 lA as the passive layer was repeatedly formed and destroyed during sliding. This range of current, also known as passivation current (I PASS ), is similar to those reported in the literature [1,43,44,[52][53][54]. The fluctuating current can be explained as follows.…”

“…The temperature of the test solution was maintained at 37 ± 1°C. The standard protocol used for the tests consists of an initial stabilization period, a sliding period, and a final stabilization [41][42][43][44]. First, in order to understand the shift in the corrosion kinetics, potentiodynamic tests were conducted.…”

“…As reported in the literature, the oxide film did not change significantly before and after sliding. [43,44] R S is resistance of the electrolyte between the sample and reference electrode; R P is the charge transfer resistance at the sample surface and electrolyte interface; CPE is used in place of a capacitance due to the inhomogeneity of the passive layer [44]. Before sliding, average R S , R P , and CPE are calculated to be 267.9 ± 11.4 X, 1.1 ± 0.16 9 10 7 X, and 2.6 ± 0.4 9 10 -5 Fs , respectively.…”

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.

Recently, the use of ionic liquids (ILs) as potential solvents in dentistry has increased. Dental polymers use ionic liquids as solvents, plasticizers, surfactants, and disinfectants. Additionally, they possess antibacterial and antifungal properties. This review aimed to evaluate the potential of task‐specific liquids in dental applications. Methodology: The Scopus, PubMed, and Web of Science databases were searched electronically for studies published between May 2013 and May 2022. Relevant publications were retrieved, evaluated, and organized for data compilation. Results and conclusion: The inclusion of ILs in dental cement, resin composites, or surface modifiers on dental implants could lead to the development of novel procedures in dentistry. The influence on the durability, structural rigidity, and other physical and mechanical properties of dental materials is profound. Additionally, they have attracted the attention of dental researchers worldwide as potent antimicrobial agent. However, further research is required to determine the effects of ILs on biosafety of host cells and mechanical properties of dental materials.

The effect of fretting associated periodic cathodic potential shifts on the electrochemistry andin vitrobiocompatibility of commercially pure titanium

2015

This study explored how periodic cathodic polarization of commercially pure titanium (cpTi) alters its electrochemical properties and biocompatibility. MC3T3-E1 preosteoblast cells were cultured directly on cpTi samples and maintained at open circuit potential (OCP) for 24 h followed by an additional 24-h sequence of periodic cathodic polarization to -1000 or -750 mV (vs. Ag/AgCl) for 1 s followed by a 5-s recovery at OCP. Control experiments were performed where the samples were maintained at OCP throughout the entire test. Subsequent electrochemical impedance spectroscopy revealed both of the periodic cathodic polarization conditions significantly reduced the polarization resistance (R ), while only the -1000 mV condition significantly increased the capacitance (C) as compared to the controls. Scanning electron micrographs showed that the cells were fragmented and balled up on the samples periodically shifted to -1000 mV as compared to the cells that were well spread on the controls and samples periodically shifted to -750 mV. Additionally, live/dead fluorescence microscopy revealed that periodic polarizations to -1000 mV reduced cell viability to around 12% as compared to the greater than 95% cell viability observed on the controls and samples periodically polarized to -750 mV. This work showed that periodic cathodic potential shifts can notably alter the electrochemical behavior of cpTi and the viability and morphology of cells seeded directly onto its surface. © 2015 Wiley Periodicals, Inc.
