Titanium nitride coatings in clinical dentistry

Journal of Dentistry, 1992
Titanium and its alloys are increasingly important in dentistry. Thin titanium nitride (TiN) coatings improve properties of metallic material for industrial purposes. Recently TiN coatings have been advocated in dentistry. In a survey of the literature, aspects of biological, mechanical and corrosive behaviour are assessed.

Titanium Nitride and Titanium Carbide as Semiconductors

Nature, 1954
IT is well known that titanium nitride shows the electric properties of a typical metal1. In fact, the specific resistivity ρ is lower than that of titanium metal itself. We have re-examined these experiments, using van Arkels's technique2 of deposition from the vapour phase for the preparation.

Pre-clinical evaluation of titanium nitride coated titanium material

Toxicology Mechanisms and Methods, 2012
The titanium nitride coated titanium is a material intended for the fabrication of left ventricular assist device. As per International standards, a material is subjected to pre-clinical evaluation before fabrication of a device. Toxicity/biocompatibility studies such as acute systemic toxicity, intracutaneous irritation, in vitro haemolysis and ...

Effect of plasma nitriding and titanium nitride coating on the corrosion resistance of titanium

The Journal of Prosthetic Dentistry, 2016
The passive film on the surface of titanium can be destroyed by immersion in a fluoridated acidic medium. Coating with titanium nitride (TiN) may improve the corrosion resistance of titanium.The purpose of this in vitro study was to investigate the effect of duplex treatment with plasma nitriding and TiN coating on the corrosion resistance of cast ...

Oxidation of vanadium nitride and titanium nitride coatings

Surface Science, 2007
Abstract The oxidation of vanadium nitride (VN) and titanium nitride (TiN) coatings in ultra-high vacuum has been investigated in situ by X-ray photoelectron spectroscopy. On the VN coatings mixed oxide layers containing V3+ and V4+ species form at elevated temperatures (⩾600°C) and at high oxygen exposures, which cover completely the VN surface ...

Development of chromium nitride coatings substituting titanium nitride

Surface and Coatings Technology, 1996
Abstract The deposition of chromium nitrides by reactive magnetron sputtering on machine parts seems to be very promising, because the mechanical properties are similar to those of TiN hard coatings. Especially the corrosion resistance of CrN is an interesting aspect related to the known problems of TiN films.

Osbornite, meteoritic titanium nitride

Mineralogical Magazine and Journal of the Mineralogical Society, 1941
Nevil Story-Maskelyne described in 1870 the mineral constituents of the Bustee meteorite, which was observed to fall in 1852 near Bustee about 45 miles west of Goruckpur, India. The stone, weighing 1429 grams, now preserved in the British Museum collections, was found to consist chiefly of enstatite and diopside, and two constituents proved to be new ...

The production of titanium nitride by the carbothermal nitridation of titanium dioxide powder

Journal of the European Ceramic Society, 1991
Abstract Titanium dioxide powders have been nitrided using a nitrogen-5% hydrogen gas mixture in the presence of carbon at temperatures between 1200 and 1500°C. The rate of titanium nitride formation is sensitive to the titanium dioxide particle surface area, and the morphology of the product corresponds closely to that of the starting oxide ...

Chlorination Kinetics of Titanium Nitride for Production of Titanium Tetrachloride from Nitrided Ilmenite

Metallurgical and Materials Transactions B, 2017
The kinetics of chlorination of titanium nitride (TiN) was investigated in the temperature range of 523 K to 673 K (250 °C to 400 °C). The results showed that the extent of chlorination slightly increased with increasing temperature and decreasing particle size of titanium nitride at constant flow rate of N2-Cl2 gas mixture.
