Spring applications require materials that possess a low Young’s modulus and high strength, in addition to having a lower alloying percentage for reduced costs. In this study, a new low-cost ¢-type titanium alloy with a lower alloying percentage than conventional ¢-type alloys was developed for spring applications using [Al]eq and [Mo]eq. The alloy is located in the near-¢ region and its ¢ tran...

The aim of the study was to compare the connective tissue response of Lewis rats to Ti, NiCr and AgPd alloys. It was found that implants were covered by collagen-rich, well vascularized capsules. Titanium was covered by the thinnest capsule (57 ± 20 μm) and AgPd alloy was covered by the thickest capsule (239 ± 50 μm). The PCNA+ cell prevalence in the capsules was lower for titanium than for AgP...

This paper proposes an exploratory study on the preparation of titanium-based superalloys through Ti+Al+Ti2AlNb three-component hybrid hot press sintering method. Through experiment mixed powder under different heating and processes, plastic deformation behavior material is carried out this basis Research, preliminarily discuss constitutive relationship new high-temperature titanium alloy Ti-Al...

A biomimetic approach for coating titanium-containing alloys with hydroxyapatite (HA) is reported in the article. Two types of Ti-containing alloys were chosen as an object for coating: Ti-6Al-4V (recommended for orthopedic application) and a novel highly biocompatible Ti-Zr-Nb alloy, with good mechanical compatibility due to a modulus that is more close to that of human bones (E ≈ 50 GPa inste...

UNLABELLED The interest in using titanium to fabricate removable partial denture (RPD) frameworks has increased, but there are few studies evaluating the effects of casting methods on clasp behavior. OBJECTIVE This study compared the occurrence of porosities and the retentive force of commercially pure titanium (CP Ti) and cobalt-chromium (Co-Cr) removable partial denture circumferential clas...

An investigation was made of the adhesion, growth and differentiation of osteoblast-like MG-63 and Saos-2 cells on titanium (Ti) and niobium (Nb) supports and on TiNb alloy with surfaces oxidized at 165°C under hydrothermal conditions and at 600°C in a stream of air. The oxidation mode and the chemical composition of the samples tuned the morphology, topography and distribution of the charge on...

Laser cladding process was performed on a commercial Ti-6Al-4V (α + β) titanium alloy by means of tungsten carbide-nickel based alloy powder blend. Nd:YAG laser with a 2.2-KW continuous wave was used with coaxial jet nozzle coupled with a standard powder feeding system. Four-track deposition of a blended powder consisting of 60 wt % tungsten carbide (WC) and 40 wt % NiCrBSi was successfully mad...

The mechanical properties of the Akers type clasp, bar and frame made by the newly developed Ti-20Cr-0.2Si alloy were studied in order to obtain the indices for designing the cast partial denture base. In the case of the clasp, the bending strength of the Ti-20Cr-0.2Si alloy and pure Ti was lower than that of the Co-Cr alloy. The Ti-20Cr-0.2Si alloy and pure Ti may have the same retentive force...

Abstract The article presents studies of the influence titanium on microstructure and mechanical properties zinc casting alloy ZL2. positive effect its addition strength die castings made this was found. Castings with had a fine structure higher tensile (approx. 255 MPa for an Ti addition) compared to base material 200 MPa). modifier also increased hardness obtained from 100 HBW (ZL2) 130 (allo...

The present paper describes the results of tests on the influence of human saliva and its substitutes on tribological characteristics of implant materials on the example of the Ti-6Al-4V (a-Ti) titanium alloy. The saliva substitutes were prepared on the basis of pyrophosphates and mucins dissolved in saline buffer. The results of the presented tribological tests show that the values of the para...
