“…In the present study, the content of V was comparable in both abutments. Hence, other authors reported that this element (a known β-stabilizer) increased the dissolution (in H 2 SO 4 ) of the oxide layer due to the defects and ionic conductivity, which increased when the alloying elements (i.e., V) diffused into the oxide layer [19,48]. Consequently, the corrosion of the alloy increased.…”

“…Therefore, the efficiency of the passivating layer is reduced [47]. Interestingly, it was suggested that the detrimental effect of Al (inducing corrosion) in HCl might dominate over other factors [48].…”

“…It supports the abovementioned hypothesis that V, being a β-stabilizer, decreases the corrosion resistance. Interestingly, studies have presented inconclusive results on whether the α-phase [5,50] or the β-phase [48] had a more detrimental effect on corrosion resistance in HCl. One study suggested that due to the harmful effect of Al (inducing corrosion), the α-phase is preferentially dissolved in HCl relative to the β-phase of Ti 6 Al 4 V [48].…”

Metals subjected to the oral environment are prone to corrosion over time and this can be harmful. Metallic restoration components such as dental subgingival implant abutments are exposed to pH changes and different ions while in contact with saliva. The aim of the study was to evaluate the corrosion resistance of titanium dental implant abutments and to compare and contrast the surface characteristics of these alloys before and after corrosion. The corrosion examination (Ecorr, jcorr, OCP, polarization curve) of two implant abutments (TiDesign EV, Astra Tech, Dentsply, York, PA, USA; Individual Titanium Abutment, Apollo Implants Components, Pabianice, Poland) was performed in 0.9% NaCl and 5% HCl. Moreover, specimens were investigated using SEM-EDS before and after the corrosion test. The value of jcorr in NaCl was higher for Astra (34.2 × 10−8 ± 2.5 × 10−8 A/cm2) than for Apollo (8.8 × 10−8 ± 2.5 × 10−8 A/cm2). Whereas, in HCl, the opposite relationship was observed (Astra 2.9 × 10−4 ± 0.8 × 10−4 A/cm2 and Apollo 62.7 × 10−4 ± 9.3 × 10−4 A/cm2). An average reactive anodic current density in NaCl for Astra amounted up to ~0.2 × 10−5–1.5 × 10−5 A/cm2, while for Apollo-up to ~3.3–9.7 × 10−7 A/cm2. The composition of both alloys after corrosion in NaCl demonstrated some changes: a decrease in the Ti, and Al and an increase in oxygen content. Hence, both alloys after corrosion in HCl demonstrated some minor changes in the elemental composition. Based on the results it can be concluded that: 1. Astra and Apollo abutments revealed good corrosion resistance and a passivation layer on the surface. 2. Apollo abutments exhibited better corrosion resistance in a neutral environment, suggesting that Astra abutments were found to be more resistant to corrosion in an acidic medium.

“…Retrieval studies show evidence of chemically induced corrosion of the Ti-6Al-4V 𝛼 phase and recently published in vitro studies show that 𝛼 may be targeted for preferential dissolution. [7,9,54] More in vitro work is needed to confirm this hypothesized in vivo mechanism. Future studies will evaluate the cyclic effect of cathodic activation and inflammatory species on the oxide capacitance and R p .…”

Deep Neural Network Predicts Ti‐6Al‐4V Dissolution State Using Near‐Field Impedance Spectra

Retrieval studies document Ti‐6Al‐4V selective dissolution within crevices of total hip replacement devices. A gap persists in the fundamental understanding of Ti‐6Al‐4V crevice corrosion in vivo and its impact on local impedance. Previous studies use nearfield electrochemical impedance spectroscopy (nEIS) for characterization of retrieved CoCrMo surfaces and phase angle symmetry‐based EIS (sbEIS) for rapid data acquisition. In this study, these methods are combined with a deep neural network to characterize the local impedance changes after selective dissolution. It is hypothesized that structural changes occurring during dissolution will manifest as property changes to the oxide film capacitance. First, after sustained cathodic activation, the Ti‐6Al‐4V β phase selectively dissolves from the surface. Next, nEIS acquires n = 100 control and n = 105 dissolved spectra. Over dissolved regions, oxide capacitance significantly increases (Log10Q = ‐4.17 versus ‐4.78 (Scm−2(s)α), p = 0.000). Using single frequency EIS (5000 Hz), a capacitance‐based scanning impedance microscopy method identifies dissolved regions within seconds. Finally, Bode phase plots of the 205 control and dissolved nEIS spectra are input into a deep neural network. After training with n = 180 spectra, the model predicts the surface state for n = 25 previously unseen nEIS spectra with 96% accuracy.

“…For Ti6Al4V, the total volume and weight loss were found to be similar, whereas Ti-E ano possesses higher corrosion mass loss (Kc) and higher oxygen concentration than Ti-E cath . The applied anodic potential (500 mV) is considered a corrosion-accelerated condition [28,34,48], which can explain the fact that Ti-E ano showed the highest Kc among all potentials. However, 500 mV is in the range of the repassivation potential for Ti6Al4V [30], and it was reported that the thickness of the passive film created on Ti alloys is proportional to the applied potential [49–52], meaning that the regrowth of the passive layer is encouraged under anodic conditions, which can be supported by the high oxygen concentration from EDS.…”

Carbide-derived carbon (CDC) was previously proposed as a surface modification method for hip implant applications since it showed excellent tribocorrosion performance under opencircuit potential (OCP) conditions. Nonetheless, a systematic evaluation of the CDC's tribocorrosion properties was still missing. Therefore, our objective is to test CDC's tribocorrosion performance under various electrochemical conditions and to identify the synergism between wear and corrosion. Based on the findings, the variations in OCP for CDC (0.626 mV) are smaller than Ti6Al4V (1.91 mV), and CDC showed lower induced current than T6Al4V for all potentials, suggesting CDC is more stable than Ti6Al4V under tribocorrosive conditions. Eventually, the weight loss of Ti6Al4V (50.662 ± 5.19 μg) was found to be significantly higher than that of CDC (4.965 ± 5.19 μg), which agrees with the electrochemical results. In summary, CDC showed better tribocorrosion performance than Ti6Al4V and was determined as an Antagonism regime.
