“…When the pH is between 4 and 10, the b c of TA2 in the simulated seawater is nearly invariant and independent of pH values at about 200 mV. This result is consistent with the findings of other studies [26,27]. When the pH is 1, the b c of TA2 obviously decreases and has a value of 150 mV.…”

“…The passivation zone of each curve is divided into two regions at about 1.5 V (vs. SCE). This behavior can be attributed to the changes in the composition and structure of the passive film [23][24][25][26]. Accordingly, variations in corrosion potential (E corr ) and passive current density (i pass ) obtained from potentiodynamic polarization curves of TA2 in simulated seawater with different pH values are shown in Table 1 and Figure 2a.…”

The effect of pH on the corrosion and repassivation behavior of TA2 in simulated seawater was studied using electrochemical tests, immersion experiments, and surface morphology topology analysis. The results show that Ecorr and Rf increased while ipass and weight loss rate decreased as the pH of simulated seawater increased. The TA2 passive film was determined to be mainly composed of a large amount of TiO2 and a small amount of TiO. The repassivation function of TA2 can be expressed as E = −0.1375 + 0.0532ln(t − 1.241) for a simulated seawater pH of 8.2. The parameter b, which represents the slope of the potential–time curve during the friction electrode test, was used to evaluate the repassivation behavior of TA2. The increase in pH value was observed to promote the repassivation speed of the passive film, which is beneficial to the corrosion resistance of TA2.

“… 12 Increasing temperature has a small influence on the cathodic reaction, but accelerates the anodic reaction greatly. The actual anodic current density could be observed after the correction of the hydrogen evolution reaction (HER) 54 ( Fig. 12(d) ), indicating an increment in corrosion current density and a decrement in the area of the passive potential region with increasing temperature.…”

“…According to many studies into the oral environment, the presence of chloride and fluorine can change the corrosion resistance of metals [5,[8][9][10][11]. Furthermore, pH variations, bacterial plaque biofilm, temperature disturbances, food intake, and implant micromovement, including other variables, can also reduce the corrosion resistance of these alloys [5,9,10].…”

Dental implant systems are composed of an implant, prosthetic components, and a crown. Since the implants are made of commercially pure Ti (cp Ti) and prosthetic components are often made of Ti and CoCrMo alloys, a galvanic couple between these two devices may lead to galvanic corrosion, ions release, and even loss of the implant. This study aimed to investigate the corrosion resistance and measure the galvanic potential between cp Ti alloys (annealed microstructured cp Ti G4 and cold-worked nanostructured cp Ti G4) and a CoCrMo alloy. The corrosion resistance has been characterized by measuring the open circuit potential, the potentiodynamic polarization, the potentiostatic polarization, and the zero-resistance current. The cp Ti has been tested before and after a surface acid treatment. The samples’ surfaces have been examined by scanning electron microscopy, and their surface roughness has been measured by a 3D optical profilometer. The polarization results showed that the CoCrMo alloy showed lower corrosion resistance than cp Ti. The surface acid treatment improves dental implant corrosion resistance. The galvanic analysis showed that the cp Ti without surface treatment behaved as an anode and after the acid treatment has a cathodic behavior in relation to the CrCoMo alloy. The highest value of galvanic current was cp TiG4 acid etched in contact with CoCrMo, in pH 2 solution. The galvanic couple with the lowest current has been the nanostructured cp Ti in contact with CoCrMo alloy.
