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 ...
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 ...
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 ...
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 ...
Thermal and chemical stability of hexagonal boron nitride (h-BN) nanoplatelets
(2015)
High-temperature properties of boron nitride platelets (200-800 nm in width and 30-50 nm in thickness) were systematically evaluated through thermogravimetric analysis (TGA) in combination with differential scanning ...
Effect of Cu content on the tribological performance of Cr-N coatings at high temperatures (840°C)
(Affiliation: Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Science and Eng., University of Illinois at Urbana-Champaign, Urbana, IL, United StatesAffiliation: Institute for Health and Consumer Protection, Joint Res. Centre of the European Commission, Ispra (VA), ItalyCorrespondence Address: Polychronopoulou, K.Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, Cyprus, 2010)
Cr-N and Cu-Cr-N coatings with Cu content between 3-65 at.%, Cu/Cr ratios in the 0.04-4.5 range and 21-27 at.% N, synthesized by twin e-beam Physical Vapor Deposition (EBPVD) at 450°C, were investigated. Using X-ray ...
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 ...
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 ...
