Abstract:
Currently, for dental implantology, structures from porous permeable materials based on titanium and titanium nickelide have been proposed and substantiated. The main advantages of titanium in comparison with other medical materials based on metals and alloys (stainless steel, alloys based on cobalt, chromium, nickel) are high elasticity, sufficient mechanical strength, and increased corrosion resistance in biological media. Porous titanium also retains these qualities. However, titanium, including porous titanium, has some disadvantages: low shear resistance, low wear resistance, and increase

Relationship between the macroscopic and local strains of porous metals is examined by microstructural observation. Open-cell porous titanium with 60% porosity was compressed up to 30% macroscopic strain at room temperature. Open-cell porous nickel with 95% porosity was compressed up to 40% macroscopic strain at room temperature. Local strains in cell walls of both porous titanium and nickel were evaluated by electron backscatter diffraction (EBSD). Absolute value of the local strain increased with increasing the macroscopic strain and it is smaller than that of macroscopic strain. In addition

The article presents information on the study of the effect of small iron and molybdenum additives on the phase composition of a powder alloy based on titanium and nickel. The authors found that the presence of unreacted pure components (titanium and nickel) indicates the incompleteness of the diffusion interaction process and the need to adjust the sintering mode of porous samples. Additives of 2.5% and 4.0% iron, as well as 2% molybdenum act as an inhibitor on the sintering process of porous samples.

Porous equiatomic Nickel-Titanium (NiTi) is a strong candidate material for bone engineering applications because its mechanical properties are within the range of bone and its porosity allows for biologic interlock of the material to the surrounding tissue.

Abstract:
Objectives. To analyze issues of surgical treatment of complicated spondylolisthesis in the lumbar spine. Materials and Methods. Forty-five patients at the age of 14 to 62 years were operated on with a device for external transpedicular fixation. All patients underwent clinical, radiological and physiologic examinations. To characterize the degree of spondylolisthesis the Meyerding classification was used. Grade I and II dislocations were treated by laminectomy of a displaced vertebra, excision of scars and mobilization of a dural sack, discectomy at a pathologic level involving both end plate

Abstract:
A stable and efficient porous nickel phosphate (p-NiPO/Ti) electrocatalyst on titanium sheets was developed via electrochemical deposition and low-temperature phosphatization. For obtaining the optimal performance of the p-NiPO/Ti electrocatalyst, the optimized experimental parameters of deposition and phosphatization were determined by parallel experiments. After the preparation, XPS and XRD were used to validate the chemical and amorphous structure, with SEM and TEM simultaneously validating a distinct nanosheet/nanocluster crosslinked microstructure. In particular, with phosphatization cond

This work studies the effect that argon and nitrogen atmospheres have on the structure, phase composition, cytocompatibility, and functional properties of porous NiTi alloys obtained by self-propagating high-temperature synthesis. Porous alloys obtained in the nitrogen atmosphere (NiTi-(N)) are characterized by brittle interstitial phases Ti4Ni2O(N) and the appearance of a finely dispersed TiNi3 phase in comparison with the alloy obtained in an argon atmosphere (NiTi-(Ar)). An increase in the volume fraction of the Ti4Ni2O(N) phase as well as an increase in the content of nitrogen in the surfa

AbstractWe have studied the structure and properties of porous nickel titanium (TiNi) alloys obtained upon reaction sintering of Ti and Ni powders with Co and Mo additives. It is established that Co and Mo doping additives retain the compaction of Ni powder achieved at the initial stage of sintering. The maximum deformation of porous samples loaded in the austenite state was observed upon adding Co, while the addition of Mo resulted in minimum deformation. The addition of Co leads to single-stage martensitic transformation in TiNi phase, while the addition of Mo leads to the two-stage transfor
