Oxidation of a polycrystalline titanium surface by oxygen and water
Reactions of a well-characterized polycrystalline titanium surface with oxygen and water molecules at 150–850 K were studied in UHV by X-ray photoelectron spectroscopy ( XPS), thermal desorption spectroscopy (TDS) and Fourier transform reflectance–absorption infrared spectroscopy (FT-RAIRS). At 150 K, 2 oxidizes Ti0 to TiIV, TiIII and TiII, but Ti exposure to H2O at this temperature produces on...
متن کاملModification of Silica surface by Titanium sol synthesis and characterization
Hydrophobic silica titanium nanoparticles (STNPs) were successfully synthesized by the sol-gel process using liquid modification. Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) studies were demonstrated the attachment of titanium on the silica surface. Titanium content enhanced the agglomeration of particles as shown in topography results. The N2 adsorption-desorption followed T...

متن کاملAbrading increases oxygen and hardness of titanium surface.
CP Ti was mirror-polished and then abraded with waterproof SiC papers of two different grit sizes: 16 and 3 microm. As-polished and abraded surfaces were characterized by means of EPMA, XPS, XRD, and hardness test. Oxygen in the mirror-polished surface was uniformly distributed at the lowest level. Comparatively, abrading with SiC papers increased the surface oxygen amount and hardness. Owing t...
متن کاملSurface modification for titanium implants by hydroxyapatite nanocomposite
Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...
