a series of tialon coatings were synthesized in a gaseous mixture of argon, nitrogen and oxygen by cathodic arc evaporation method using a ti–al mosaic target. oxidation of coatings was carried out by heating the coated samples at the temperatures of 500, 600, 700, and 800°c for 1 h in air atmosphere. it was found that heat treatment changed the microstructure and composition of the coating. th...

Operation of the nonaqueous Li-O2 battery critically relies on the reversible oxygen reduction/evolution reactions in the porous cathode. Carbon and polymeric binder, widely used for the construction of Li-O2 cathode, have recently been shown to decompose in the O2 environment and thus cannot sustain the desired battery reactions. Identifying stable cathode materials is thus a major current cha...

In order to meet the design requirements of lightweight artillery and adopt method double-glow plasma nitriding solve problem low hardness poor abrasion resistance Ti alloy, BTi-62421S high-performance titanium (Ti) alloy was selected as experimental material replace gun steel. To study effect different nitrogen (N) concentrations on heat scouring performance investigate influence alloying elem...

The application of implants for dental and orthopedic surgery has increased rapidly within the past few decades. In craniomaxillofacial surgery, different implant systems have been applied, for example, for dental and bone replacement or osteosynthesis plates and screws. These implants may be made of pure titanium or a titanium alloy, usually titanium-aluminumvanadium (Ti-6Al-4V). The surface c...

This paper discusses the results of a study focused on nature interaction Me-MeN-(Me,Mo,Al)N coatings (where Me = zirconium (Zr), titanium (Ti), or chromium (Cr)) with contact medium based Ni-Cr system. The studies were carried out during turning nickel–chromium alloy at different cutting speeds. hardness was found, and their nanostructure phase composition studied. experiments conducted using ...

A magnetocaloric effect (MCE) with sizable isothermal entropy change (ΔS) maintained over a broad range of temperatures above the blocking temperature is reported for rare earth-free superparamagnetic nanoparticle system comprising Fe–TiN heterostructure. Superparamagnetic iron (Fe) particles were embedded in titanium nitride (TiN) thin film matrix TiN/Fe/TiN multilayered pattern using pulsed l...

Diffusion and chemical reactions in multicomponent systems play an important role in numerous technology applications. For example, surface treatment of materials and coatings by particle beam leads to chemical composition and grain structure change. To investigate the thermal-diffusion and chemical processes affecting the evolution of surface structure, the mathematical modeling is efficient a...

Metal nitrides have been proposed to replace noble metals in plasmonics for some specific applications. In particular, while titanium nitride (TiN) and zirconium nitride (ZrN) possess localized plasmon resonances very similar to gold in magnitude and wavelength, they benefit from a much higher sustainability to temperature. For this reason, they are foreseen as ideal candidates for applications...

This Letter is about the role of bottom electrode in resistive switching SiNx-based random-access memory. Titanium nitride (TiN) and platinum (Pt) are used as electrodes to fabricate devices whose I–V characteristics compared. The with Pt have digital behavior a main memory window. However, TiN provide an analog gradual operation. We propose that this difference due different work functions top...

Interaction between 5 lm thick copper and 50 nm thin titanium films was investigated as a function of annealing temperature and time using MeV He Rutherford backscattering, X-ray diffraction and dynamic Secondary Ion Mass Spectrometry. Samples were made by depositing 10 nm of titanium on a PECVD silicon oxynitride, followed by 50 nm of titanium nitride and 50 nm of titanium in the said order. I...
