Structure, mechanical and tribological properties of sputtered TiAlBN thin films
(1999)
TiAlBN films were produced by simultaneously sputtering from TiAl and TiB2 targets in Ar/N2 mixtures at a substrate temperature of 150 °C. The goal of this investigation was to study the influence of the nitrogen content ...
The effect of boron additions on the tribological behaviour of TiN coatings produced by electron-beam evaporative PVD
(1999)
TiN coatings containing small amounts of boron were synthesized by electron beam evaporating a Ti-B alloy material from a single crucible source into a plasma comprising Ar or an Ar/N2 mixture at a substrate temperature ...
Deposition and characterisation of carbon-containing tungsten coatings prepared by reactive magnetron sputtering
(1998)
Carbon-containing tungsten coatings were deposited by magnetron sputtering onto AISI 316 stainless steel substrates in Ar/C2H2 gas mixtures. Optical emission spectroscopy was used to control the C2H2 gas flow. The goal of ...
Room temperature synthesis and high temperature frictional study of silver vanadate nanorods
(2010)
We report the room temperature (RT) synthesis of silver vanadate nanorods (consisting of mainly β-AgVO3) by a simple wet chemical route and their frictional study at high temperatures (HT). The sudden mixing of ammonium ...
X-Ray diffraction investigations of magnetron sputtered TiCN coatings
(1995)
X-ray diffraction measurements were performed on titanium carbonitride coatings produced in an electron enhanced, unbalanced magnetron system. The films were deposited onto AISI 316 stainless steel substrates with an argon ...
Microstructural and morphological effects on the tribological properties of electron enhanced magnetron sputtered hard coatings
(1995)
X-ray diffraction measurements and scanning electron microscopy studies on close to stoichiometric titanium carbonitride [TiCxN(1 _x)] and carbon containing tungsten coatings produced in an electron enhanced unbalanced ...
Layered atomic structures of double oxides for low shear strength at high temperatures
(2010)
Double oxide phases combining a transition metal and a noble metal have recently become a subject of investigation as solid lubricant materials for high-temperature tribological applications. Here, we study the changes in ...
Tensile mechanical properties and hydraulic permeabilities of electrospun cellulose acetate fiber meshes.
(2012)
The mechanical properties and hydraulic permeabilities of biomaterial scaffolds play a crucial role in their efficacy as tissue engineering platforms, separation processors, and drug delivery vehicles. In this study, ...
Mechanical and high pressure tribological properties of nanocrystalline Ti(N,C) and amorphous C:H nanocomposite coatings
(2010)
This paper reports on the mechanical and high pressure tribological properties of nanocrystalline (nc-) Ti(N,C)/amorphous (a-) C:H deposited, using low temperature (∼200°C) DC reactive magnetron sputtering. The mechanical ...
Solvothermal synthesis, nanostructural characterization and gas cryo-adsorption studies in a metal–organic framework (IRMOF-1) material
(2017)
A nanoporous metal–organic framework material, exhibiting an IRMOF-1 type crystalline structure, was prepared by following a direct solvothermal synthesis approach, using zinc nitrate and terephthalic acid as precursors ...
