Ti-Ta alloys are potentially interesting for many applications including chemistry industries, marine environment and biomedical devices. In this study, the were synthesized by cold crucible levitation melting (CCLM) in whole range of composition. The different microstructures characterized X-ray diffraction optical microscopy, β-transus was detected electrical resistivity, mechanical properties evaluated compression tests microhardness measurements electrochemical behavior carried out...
New beta‐metastable Ti alloys containing Ta, Mo and Fe biocompatible elements were synthesized by arc melting then quenched in water from the beta phase field. For each alloy, decomposition was characterized electric resistivity measurements differential scanning calorimetry upon heating room temperature to transus. The formation of omega alpha nanophases detected observed different transitions behavior discussed connection with beta‐stabilizer content alloy.
Abstract In this study, a new Ti‐25Ta‐25Nb (mass%) β alloy was synthesised by cold crucible semi‐levitation melting. After melting, each ingot solution treated in the β‐phase domain and water quenched order to obtain fully recrystallised homogeneous microstructure. To evaluate bio‐corrosion property of alloy, corrosion tests (cyclic potentiodynamic linear polarisation, EIS) surface analysis (SEM) were carried out Ringer at different pH values (acid, neutral basic). The results indicated that...
To enhance their longevity, dental implants must be highly biocompatible and have a low elastic modulus close to that of the bone. They also possess high superficial hardness corrosion resistance. For these reasons, recently developed low-modulus Ti-27Nb alloy with nontoxic elements was treated by gas nitriding at temperature in this study. A very thin nitrided layer 0.5 μm thickness followed an enriched nitrogen zone observed. Consequently, evaluated about 1800 HV obtained surface, which...
Abstract Corrosion behaviour of the new TiMo alloys together with currently used metallic biomaterials commercial pure titanium (Cp‐Ti) was investigated for dental applications. Ingots composition Ti12Mo, Ti20Mo and Ti40Mo were synthesized by cold crucible levitation melting (CCLM) technique. All samples examined using electrochemical techniques: open circuit potential, potentiodynamic polarization curves impedance spectroscopy (EIS) in two media: artificial saliva mouthwash solution 450 ppm...
Abstract By anodic potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques, the effect of recrystallization on corrosion behaviour Ti12Mo Ti12Mo5Ta alloys was studied. Aerated Ringer's solution employed as electrolyte at 37 °C. The pH 6.9 adjusted to 2.5 simulating disease state. results show excellent resistance for recrystallized alloys, corroborated by high values low passive current density. Recrystallized structure rendered extremely resistant.
