“…32,33 In addition, as mentioned above, LPS and VSCs released form P. gingivalis could potentially promote titanium corrosion. 16 Thus, the higher degree of bacterial attachment, as well as the enhanced corrosion, may lead to more changes on the SLA titanium surface, including roughness and wettability. The biocorrosion behavior on pure and SLA titanium surfaces caused by P. gingivalis was investigated by electrochemical techniques.…”

“…14 Furthermore, it had been detected at higher number from microbial lms around implants in patients with peri-implantitis. 15,16 And P. gingivalis had been found to attach on titanium surfaces in large amounts during the process of biolm formation on titanium surfaces. 17,18 Meanwhile, P. gingivalis has several virulence factors like lipopolysaccharides (LPS) and releases volatile sulfur compounds (VSCs) as a result of its metabolism, which can potentially promote titanium corrosion.…”

Titanium and its alloys have been widely used as implant materials due to their excellent mechanical property and biocompatibility. In the present study, the effect of glucose concentration on corrosion behavior of pure titanium TA2 in Hanks’ simulated body fluid is investigated by the electrochemical impedance spectrum (EIS) and potentiodynamic polarization methods. The range of glucose concentrations investigated in this research includes 5 mmol/L (limosis for healthy people), 7 mmol/L (after diet for healthy people), 10 mmol/L (limosis for hyperglycemia patient), and 12 mmol/L (after diet for hyperglycemia patient), as well as, 15 mmol/L and 20 mmol/L, which represent different body fluid environments. The results indicate that the pure titanium TA2 demonstrates the best corrosion resistance when the glucose concentration is less than 10 mmol/L, which shows that the pure titanium TA2 as implant material can play an effective role in the body fluids with normal and slight high glucose concentrations. Comparatively, the corrosion for the pure titanium implant is more probable when the glucose concentration is over 10 mmol/L due to the premature penetration through passive film on the material surface. Corrosion defects of pitting and crevice exist on the corroded surface, and the depth of corrosion is limited to three microns with a low corrosion rate. The oxidation film on the surface of pure titanium TA2 has a protective effect on the corrosion behavior of the implant inner material. The corrosion behavior of pure titanium TA2 will happen easily once the passive film has been penetrated through. The corrosion rate for TA2 implant will accelerate quickly and a pure titanium implant cannot be used.

“…Based on an excellent combination of high tensile strength to weight ratio and good corrosion behavior, hardenability, and fatigue crack growth resistance, [1][2][3][4][5][6][7][8] titanium alloys are regarded as a superior and cost-effective structural materials for widely applications in aerospace, [9] marine, [10] industrial, [11] and commercial fields. [12] Hydrogen is of great interest to the energy industry as a sustainable clean energy source, and various hydrogen utilization systems have been developed to promote the widespread adoption of fuel cell vehicles or stationary fuel cell systems that used hydrogen.…”

The Hydride Precipitation Mechanisms in the Hydrogenated Weld Zone of Ti–0.3Mo–0.8Ni Alloy Argon‐Arc Welded Joints

A review of the microstructural evolution and phase transformation in the hydrogenated weld zone of Ti-0.3Mo-0.8Ni alloy argon-arc welded joints has been considered. The role of crystallographic, microstructural, and precipitation mechanisms on the defect-free properties of the hydrogenated weld zone has been analyzed, and hydride phase formations have been revealed by the influence of hydrogen on the microstructural characteristics of the weld zone. The results show face-centered cubic (FCC) δ and face-centered tetragonal (FCT) γ hydride phase formations are found in the hydrogenated 0.21 wt% H weld zone. Large lamellar, slender plate δ and long needle γ hydrides can only precipitate from the alpha lamellae, and not from the transformed beta phase due to the high hydrogen solubility found in the beta phase. Formation of the δ and γ hydrides are the result of α H phase separation reaction: α H ! α (H lean region) þ δ (H rich region) and α H ! γ (H rich region), respectively. The precipitation mechanisms and characteristics of the δ and γ hydrides formed in alpha phase are discussed in detail. Dislocation multiplication around the hydrides is promoted effectively by hydrogen addition, the fact that the quantity of dislocations around the δ hydride increased obviously compared to γ hydride indicated the α H ! δ phase transformation result in a greater volume expansion rate.
