The lifetimes and the premature wear of machining tools impact on manufacturing efficiencies and productivities. A significant proportion of machining tool damage can be attributed to component wear. Here, titanium aluminium nitride (TiAlN) multi-layered with titanium diboride (TiB2) prepared by PVD (Physical Vapour Deposition) sputtering onto H-13 substrates are studied as potential wear-resis...

A thin film coating of titanium nitride was applied to the surface of rf cavity tuners to reduce secondary electron generated when the existing copper base material is in place. The tuners are used in high-field gradients, where electron heating of the tuner is a problem. By reducing the generation of electrons the temperature of the tuners will be reduced, for better reliability. This paper co...

The main purpose of the research was to develop the micromodel of biocompatible titanium nitride nanocoating deposited on polymer by pulsed laser deposition method in blood chambers of Polish ventricular assist devices: POLVAD and POLVAD_EXT. The analysis of the parameters of micromodel crucial for the phenomenon of loss of cohesion occurring between coating and substrate was carried out as wel...

Films of titanium nitride deposited by physical vapor deposition on 304 L stainless steel substrates were hot isostatic pressed (HIP) under 150 MPa at 550 °C. To study the effects of this treatment on the microstructure of those films, X-ray diffraction analyses, Rutherford Backscattering spectroscopy, scanning electron microscopy, and atomic force microscopy were performed. Surface hardness, a...

A broadband metamaterial absorber (MA) composed of hexagonal-arranged single-sized titanium nitride (TiN) nano-disk array and monolayer molybdenum disulfide (MoS2) is studied using finite-difference time-domain (FDTD) simulations. The structure of TiN nano-disk array/dielectric silica (SiO2)/aluminum (Al) is adopted in our design. By optimizing the dimension parameters of the structure, an aver...

Superior coating technology and roller materials such as M50 steels (0.8C–4.2Cr–4.3Mo–1V wt. %) (1.0C–2.0Cr–0.5Mo–1.0Mn– 0.5Si are well recognized in modern technology. The aim is to present all the external internal parameters that affect rolling system by taking into consideration microstructure importance identifying service life of technique. most dangerous defects cracks wear...

22 Abstract 23 24 Surface chemistry and film growth were examined during titanium nitride (TiN) atomic layer deposition (ALD) using sequential 25 exposures of tetrakis-dimethylamino titanium (TDMAT) and NH . This ALD system is shown to be far from ideal and illustrates 3 26 many potential problems that may affect ALD processing. These studies were performed using in situ Fourier transform infra...

We report the growth of titanium nitride microcolumns under multipulse Nd:yttrium aluminum garnet ( 1.064 m, ∼ 300 ns, 30 kHz) laser irradiation of titanium targets in nitrogen atmosphere. The laser intensity value was chosen below the single-pulse melting threshold of titanium. The evolution with the number of laser pulses of the target morphology, crystalline state, and chemical composition a...

Titanium-based nitride physical vapour deposition (PVD) coatings, such as titanium (TiN), are state-of-the-art solutions for surface modifications of CoCrMo-based implants patients who hypersensitive to metallic ions cobalt, chromium and nickel. Variations the process parameters during cathodic arc evaporation known exhibit an impact on properties coatings. The aim this study was characterise e...

Titanium nitride (TiN) not only was utilized in the wear-resistant coatings industry but it was also adopted in barrier processes for semiconductor manufacturing. Barrier processes include the titanium (Ti) and TiN processes, which are commonly used as diffusion barriers in via/contact applications. However, engineers frequently struggle at the via/contact module in the beginning of every techn...
