The microstructures and the phase transformation temperatures of sputtered titanium–nickel (TiNi) thin films, both free-standing and attached on different underlying multi-layer substrates, have been studied. Differences in the microstructures, such as the lattice constants and relative concentrations of TiNi, Ti2Ni and TiNi3 phases, have been observed among the free-standing and the attached f...

Recently, the defect-induced static magnetic behaviours of nanomaterials have been a cutting-edge issue in diluted magnetic semiconductor materials. However, the dynamic magnetic properties of nanomaterials are commonly ignored if their bulk counterparts are non-magnetic. In the present research, titanium nitride-carbon (TiN/C) nanocomposites were found to exhibit both static and dynamic magnet...

Surfaces of medical implants can be enhanced with the favorable properties of titanium-nitride (TiN). In a review of English medical literature, the effects of TiN-coating on orthopaedic implant material in preclinical studies were identified and the influence of these effects on the clinical outcome of TiN-coated orthopaedic implants was explored. The TiN-coating has a positive effect on the b...

f bstract canning electron microscopy (SEM) and differential canning calorimetric (DSC) studies were utilized to nvestigate surface and microstructure of two brands of otary nickel-titanium (NiTi) endodontic instruments, in he as-received condition and after subjection to 1, 6, nd 11 sterilization cycles. A total of 66 ProFile (n 3) and Flexmaster (n 33) files were examined. SEM bservations ind...

We report a study on the biocompatibility vs. thickness in the case of titanium nitride (TiN) films synthesized on 410 medical grade stainless steel substrates by pulsed laser deposition. The films were grown in a nitrogen atmosphere, and their in vitro cytotoxicity was assessed according to ISO 10993-5 [1]. Extensive physical-chemical analyses have been carried out on the deposited structures ...

The interface formation between different thicknesses of strontium titanate (SrTiO3) or titanium nitride ~TiN! with a 2000 Å Fe3O4 film is studied using x-ray absorption spectroscopy ~XAS! and x-ray magnetic circular dichroism ~XMCD!. Our results show that the deposition of 10–50 Å of TiN results in an immediate and substantial removal of oxygen from the near interface region, resulting in the ...

22 Abstract 23 24 Surface chemistry and film growth were examined during titanium nitride (TiN) atomic layer deposition (ALD) using sequential 25 exposures of tetrakis-dimethylamino titanium (TDMAT) and NH . This ALD system is shown to be far from ideal and illustrates 3 26 many potential problems that may affect ALD processing. These studies were performed using in situ Fourier transform infra...

Because of its superior properties, stainless steel has been widely used for many applications. Nonmetallic inclusions can influence the quality products. A set samples was to track response inclusion composition during processing a heat titanium-bearing 18% chromium steel, from deoxidation after decarburization, solidified slab. The oxide responded as expected additions deoxidizers and calcium...
