The nanostructure, wear and corrosion performance of arc-evaporated CrBxNy nanocomposite coatings
(2009)
The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS ...
Deposition and nanotribological characterization of Sub-100-nm thick protective Ti-based coatings for miniature applications
(2011)
Ti-based protective thin films with thicknesses below 100 nm, intended for miniature applications were deposited using physical vapor deposition magnetron sputtering. X-ray diffraction (XRD), scanning electron microscopy, ...
Adaptive VN/Ag nanocomposite coatings with lubricious behavior from 25 to 1000 °c
(2010)
A two-phase nanocomposite coating that consists of inclusions of silver in a vanadium nitride matrix (VN/Ag) was investigated as a potential adaptive coating with a reduced friction coefficient from 25 to 1000 °C. This ...
Spark ignitable ball milled powders of Al and Ni at NiAl composition
(2014)
Low-energy ball milling of aluminum and nickel particles with an overall composition corresponding to the NiAl intermetallic phase was performed up to milling durations of 13 h. The milled powders and cold-compacted pellets ...
Growth and structural characterization of orthorhombic and tetragonal SrCuO2 thin films
(2013)
Epitaxial SrCuO2 thin films were grown on (0 0 1) SrTiO 3 substrates by pulsed laser deposition using a stoichiometric target. X-ray diffraction indicated that the SrCuO2 films undergo a structural phase transition as a ...
Broom-like and flower-like heterostructures of silver molybdate through pH controlled self assembly
(2012)
Silver molybdate microrods are selfassembled into micron sized, broom-like and flowerlike structures. Our investigations indicate that through a simple hydrothermal process, large scale production of such structure is ...
Thermoelectric properties of nanocrystalline PbTe synthesized by mechanical alloying
(2010)
In this work, nanocrystalline lead telluride powder was synthesized from high-purity elements by mechanical alloying by means of a planetary ball-milling procedure. The milling medium was tungsten carbide, and the diameter ...
An investigation into the conversion of In2O3 into InN nanowires
(2011)
Straight In2O3 nanowires (NWs) with diameters of 50 nm and lengths ≥2 μm have been grown on Si(001) via the wet oxidation of In at 850°C using Au as a catalyst. These exhibited clear peaks in the X-ray diffraction corresponding ...
Solid-state synthesis and thermoelectric properties of Sb-doped Mg 2Si materials
(2013)
Sb-doped magnesium silicide compounds have been prepared through ball milling and solid-state reaction. Materials produced were near-stoichiometric. The structural modifications have been studied with powder x-ray diffraction. ...
Textured VN coatings with Ag3VO4 solid lubricant reservoirs
(2011)
Silver oxovanadate powders were produced using a low temperature hydrothermal synthesis method. X-ray diffraction (XRD) and Raman microscopy revealed the formation of the α-Ag3VO4 phase, and differential scanning calorimetry ...
