The properties and oxidation wear patterns in the composite nanostructured coating of Zr-ZrN-(Zr,Mo,Al)N were studied during turning Inconel 718 alloy at cutting speeds vc = 125 200 m/min. hardness coating, its elastic modulus, critical fracture load scratch testing determined. study focused on tribological temperatures 400–900 °C paired with an insert made 718, which exhibited a certain advant...

Hybrid intermetallic composites (HICs-aluminum based matrix, new hybrid design) reinforced with titanium nitride (TiN) and alumina (γ-Al2O3) were designed manufactured through the innovative combined method of sinter + forging. This results in highly dense materials with, general, improved mechanical properties. In TiN content was varied (10, 20 30 wt %) but γ-Al2O3 kept constant at 10 wt%. Add...

Abstract High optical absorptivity or a large absorption cross-section is necessary to fully utilize the irradiation of light for photothermal heating. Recently, titanium nitride (TiN) nanostructures have been demonstrated be robust absorbers in range owing their nonradiative decay processes enhanced by broad plasmon resonances. Because photothermally generated heat dissipates surroundings, sup...

The article studies the tribological properties of multicomponent nanostructured coatings Zr-ZrN-(Zr,Cr,Al)N and Zr-ZrN-(Zr,Mo,Al)N, as well wear resistance fracture behaviour cutting tools with mentioned during turning Inconel 718 alloy. Ti–TiN-(Ti,Cr,Al)N coating was also considered a reference coating. While is characterized by high hardness, it demonstrated coefficients friction (COF) at te...

We report an interesting observation of minimization of bacterial attachment on titanium nitride coatings of increased thickness. DC magnetron sputtering method was used to prepare titanium nitride coatings of different thickness and the attachment of an oral bacteria Porphyromonas gingivalis was studied. With increase in thickness of the coatings the particle size increased and the order of ba...

In this study, a plasma electrolytic oxidation (PEO) process was used to form titanium-aluminum oxide coating on aluminized steel. The present work was mainly to study the effects of treatment time of PEO process on properties of the titanium coating. A potentiodynamic polarization corrosion test was employed to investigate the corrosion resistance of the coating. The friction coefficient and w...

Boron-doped nanocrystalline diamond (BDD) electrodes have recently attracted attention as materials for neural electrodes due to their superior physical and electrochemical properties, however their biocompatibility remains largely unexplored. In this work, we aim to investigate the in vivo biocompatibility of BDD electrodes in relation to conventional titanium nitride (TiN) electrodes using a ...

We have studied the superconducting behavior of a 100 nm Titanium Nitride (TiN) thin film in a perpendicular magnetic field. We found a zero field transition temperature of 4.6 K and a slope for the transition line in the H-T plane of −0.745 T /K. At 4.2 K, we have performed careful transport measurements by measuring both the differential resistivity and voltage as a function of a DC current. ...
