Nitriding at pressures from 300 to 10−2 mm Hg with the nitrogen inflow cut off and holding at low pressure is the best method of obtaining a case of substantial depth, with satisfactory mechanical properties of the base metal.

Corrosion Behavior of Coatings of Titanium Nitride and Titanium-Titanium Nitride on Steel Substrates
Corrosion, 2006It is well known that titanium nitride (TiN) coatings produced by physical vapor deposition (PVD) have a limited corrosion resistance, as a result of their intrinsic porosity. Some attempts have been made to improve corrosion resistance, by such measures as increasing film thickness.

Synthesis of Nanocrystalline Titanium Nitride Powders by Direct Nitridation of Titanium Oxide
Journal of the American Ceramic Society, 2001Nanocrystalline TiN powder has been synthesized by the direct nitridation of nanocrystalline TiO 2 powder. Powder XRD patterns indicated that the TiN nanocrystalline powder could be obtained by nitridation at 800°C for 5 h.

Gas nitriding of a commercial purity Grade 4 titanium at 1120°C for 5 h formed hard TiN layer (2450 HV) on the surface with a thickness of about 35 m. When compared to the as-received state, nitrided titanium exhibited excellent wear resistance along with a relatively low coefficient of friction (CoF) against Al2O3 ball under dry sliding conditions.

Titanium nitride-molybdenum metallizing method for aluminium nitride
Proceedings. Japan IEMT Symposium, Sixth IEEE/CHMT International Electronic Manufacturing Technology Symposium, 1990A paste containing molybdenum (Mo) and titanium nitride (TiN) powders was printed on aluminium nitride (AlN) substrates and fired. The adhesive strength of substrates metallized with Ni/Au plate was about 25 kg/2.5 mm/sup 2/ and was unchanged after a thermal cycle test.

Creep of silicon nitride-titanium nitride composites
Journal of Materials Science, 1993The effect of particulate TiN additions (0–50 wt%) on creep behaviour of hot-pressed (5 wt%Y2O3 + 2 wt%Al2O3)-doped silicon nitride (HPSN)-based ceramics was studied. Creep was measured using a four-point bending fixture in air at 1100–1340 °C. At 1100 °C, very low creep rates of HPSN with 0–30 wt% TiN are observed at nominal stresses up to 160 MPa. At

Oxidation of vanadium nitride and titanium nitride coatings
Surface Science, 2007Abstract 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 ...

Sunlight absorbing titanium nitride nanoparticles
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015The surface plasmon resonances of titanium nitride nanoparticles are broad and covers majority of the solar spectrum. In terms of integrated absorption efficiency titanium nitride nanoparticles are efficient sunlight absorbers due to these resonances, even better than gold and carbon nanoparticles which have been extensively studied so far.

Abstract An interaction between nitrided titanium and a hydrogen plasma prepared using an r.f. discharge was studied. Weight gain measurement, X-ray diffraction examination, electron spectroscopy for chemical analysis and laser microprobe mass analysis showed that small amounts of hydrogen were absorbed on the surface of the nitrided titanium. As the

Abstract : Several compositions of cermets based on titanium nitride were investigated. The cermets were tested for strength in cross bending, resistance to oxidation, and resistance to thermal shock. The differences of the various compositions are noted as well as the effect of different processing techniques.
