In this study, metal matrix composites (MMC) of a CoCrNi medium entropy alloy (MEA) reinforced with titanium nitride (TiN) nano-sized particles were designed for production by laser-based powder bed fusion (LB-PBF). Two different additions, 0.5 wt% and 5 TiN nano- sized particles, mixed using tumbling ball milling, respectively. The results suggest that although the morphology is not significan...

TiN/AlTiN ; TiN/CrN and CrN/AlTiN multilayer coatings have been deposited by the cathodic arc evaporation technique. The period is in the range 7 – 200 nm for a total thichness of 3 μm. The period’s control of the nanoscaled hard films is achieved, a priori, by way of a simple geometrical calculation and, a posteriori, via both X-ray diffraction and transmission electron microscopy on cross-sec...

The high chemical activity, low thermal conductivity, and strength of titanium alloys lead to severe tool wear during cutting. coating applied the surface insulates effect heat reactions. TiAlSiN AlCrN are two representative coatings with excellent properties in TiN-based CrN-based applications, respectively. Three types nanocoatings—TiAlSiN monolayer, TiAlSiN/AlCrN multilayer—were prepared, mi...

We investigated layered titanium nitride (TiN) and aluminum (AlN) for color glasses in building integrated photovoltaic (BIPV) systems. AlN TiN are among suitable cost-effective optical materials to be used as thin multilayer films, owing the significant difference their refractive index. To fabricate structure, we radio frequency magnetron deposition method achieve target thickness uniformly. ...

The paper studies the structure, phase composition and properties of thermal sprayed coatings made Ti4Al titanium alloy “Ti4Al + AISI420” pseudoalloy obtained by hypersonic metallization. It is shown that deposited include in a large amount nitride TiN (up to 70 vol.%), which formed during metallization process. At same time, an increase propane pressure from 0.3 0.4 MPa leads slight decrease c...

The ferroelectric degenerate semiconductor Sn1−δTe exhibits superconductivity with critical temperatures, Tc, of up to 0.3 K for hole densities of order 10 21 cm. When doped on the tin site with greater than xc = 1.7(3)% indium atoms, however, superconductivity is observed up to 2 K, though the carrier density does not change significantly. We present specific heat data showing that a stronger ...

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed struc...

This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials. In this thesis we benc...

Due to the high energy, narrow distribution and breaking through absorption limitation, plasmon-induced hot electrons have been widely applied extend photoresponse spectra of semiconductor. In order further enhance resonance effect local plasmon based on metallic nanostructures, we used hydrofluoric stain etching method fabricate nanostructured black silicon (BSi) deposited titanium nitride (Ti...
