“…Titanium nitride is a ceramic material with large hardness (of 2000 kg/mm 2 ), elevated temperature of decomposition (of 2949C), defect structure (deviation from stoichiometry); it has superconductivity, and at room temperature, chemical stability. TiN is mostly employed as a coating to improve other materials [2].…”

Films of PVP doped with TiN nanoparticles are fabricated. The structure and optical characteristics are studied to apply the nanocomposites for industrial and bioenvironmental applications like humidity sensors, diodes, antibacterial coating, biosensors and UV-shielding. The results show that the optical characteristics are enhancing with the rising in TiN nanoparticles' ratio. The results indicate that the PVP/TiN nanocomposites may be used in various biomedical and bioenvironmental fields.Виготовляються плівки полівінілпіролідону (ПВП), леґовані наночастинками TiN. Структура й оптичні характеристики вивчаються для використання нанокомпозитів у промислових і біосередовищних застосуваннях, таких як датчики вологости, діоди, антибактеріяльне покриття, біосенсори й УФ-екранування. Результати показують, що оптичні характеристики посилюються зі зростанням співвідношення наночастинок TiN. Результати вказують на те, що нанокомпозити ПВП/TiN можуть використовуватися в різних біомедичних і біосередовищних полях.

“…Among these, various physical vapor deposition (PVD) titanium nitride (TiN) coating methods, such as sputtering and arc-ion plating, have been extensively studied and are now commercially available [5,6]. A few microns of TiN coating increases the surface hardness of the implant, improves the mechanical durability and fatigue resistance by reducing the friction coefficient, and effectively prevents metal ions from leaching into the surrounding tissue by creating a dense film resistant to acids and bases [7][8][9][10][11][12]. Since PVD is a directional deposition method, it may not uniformly cover all surfaces of the implant due to the shadow effect and often creates variations in coating thickness due to poor step coverage.…”

Application of a Novel CVD TiN Coating on a Biomedical Co–Cr Alloy: An Evaluation of Coating Layer and Substrate Characteristics

et al. 2020

Titanium nitride (TiN) was deposited on the surface of a cobalt–chromium (Co–Cr) alloy by a hot-wall type chemical vapor deposition (CVD) reactor at 850 °C, and the coating characteristics were compared with those of a physical vapor deposition (PVD) TiN coating deposited on the same alloy at 450 °C. Neither coating showed any reactions at the interface. The face-centered cubic (fcc) structure of the alloy was changed into a hexagonal close-packed (hcp) phase, and recrystallization occurred over at 10 μm of depth from the surface after CVD coating. Characteristic precipitates were also generated incrementally depending on the depth, unlike the precipitates in the matrix of the as-cast alloy. On the other hand, the microstructure and phase of the PVD-coated alloy did not change. Depth-dependent nano-hardness measurements showed a greater increase in hardness in the recrystallization zone of the CVD-coated alloy than in the bulk center of the alloy. The CVD coating showed superior adhesion to the PVD coating in the progressive scratch test. The as-cast, PVD-coated, and CVD-coated alloys all showed negative cytotoxicity. Within the limitations of this study, CVD TiN coating to biomedical Co–Cr alloy may be considered a promising alternative to PVD technique.

“…In neurology, TiN-coated electrodes are used in chronically implanted devices for the treatment of spinal cord injury. TiN-coating is also used in orthopedic implants, because of its excellent biological properties, such as the reduction of the release of cobalt-chromium-molybdenum ions, and the aesthetic appeal of the "golden color" [5]. Titanium nitride nanoparticles exhibit novel electronic, optical and mechanical properties such as high melting points and low sintering tendencies are beneficial for applications in high temperature catalysis [6].…”

Nanocomposites films of (polyvinyl alcohol-poly-acrylic acid) blend/ titanium nitride nanoparticles have been prepared by concentrations: polyvinyl alcohol (85 wt.%), poly-acrylic acid (15 wt.%) and titanium nitride nanoparticles were added to (PVA-PAA) blend with concentrations are (1.5, 3, 4.5, and 6) wt.%. The (PVA-PAA-TiN) nanocomposites were prepared by casting method for antibacterial application. The (PVA-PAA-TiN) nanocomposites were test for antibacterial against Escherichia coli (E. coli). The results showed that the (PVA-PAA-TiN) nanocomposites have antibacterial activity against Escherichia coli. The inhibition zone diameter increases with increase in TiN nanoparticles concentration.
