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 ...
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 ...
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 ...
Novel combustion synthesis of carbon foam‑aluminum fluoride nanocomposite materials
(2018)
The facile, rapid and bulk production of composite materials consisting of carbon nanostructures doped with metal-based compounds has been a significant challenge for various research areas where such types of materials ...
Tribological behavior of CrN and Al-Cr-N coatings
(Affiliation: Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678, Nicosia, CyprusCorrespondence Address: Demas, N. G.Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United States, 2009)
The tribological behavior of CrN and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was investigated. The composition, structure, mechanical and tribological properties of the coatings were determined ...
Fabrication, characterization and applications of novel nanoheater structures
(2013)
Nanoheaters are reactive nanostructures that can generate localized heat through controlled ignition. Besides the widely used nanofoil structure with multiple alternative Al-Ni layers, various new nanostructures have been ...
Few-step synthesis, thermal purification and structural characterization of porous boron nitride nanoplatelets
(2016)
Hexagonal boron nitride (h-BN) nanoplatelets with 99 wt.% purity, 900 to 2000 nm particle width, 30 to 90 nm particle thickness, 213 m2/g specific surface area (SSA), 66% micropore SSA and 0.85 nm average pore size were ...
