Tribological properties of twin electron-beam evaporated Cr-N and Al-Cr-N coatings under laboratory sliding and drill experiments
(2008)
The tribological behavior of substoichiometric Cr-N and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was studied. Al-Cr-N coatings with Al to Cr ratios in the range of 1-8 (and nitrogen concentrations ...
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 ...

This study describes the correlation between the microstructure, mechanical and tribological properties of Ti 1-xCx coatings (with x being in the range of 0-0.5), deposited by reactive magnetron sputtering from a Ti target ...
Structure, mechanical and tribological properties of nitrogen-containing chromium coatings prepared by reactive magnetron sputtering
(1999)
Cr(1-x)N(x) coatings were deposited by magnetron sputtering at a substrate temperature of 200°C onto AISI 316 stainless-steel substrates immersed in an Ar/N2 plasma. The goal of this investigation was to study the influence ...
Characterisation and tribological evaluation of nitrogen-containing molybdenum-copper PVD metallic nanocomposite films
(2005)
This paper reports on the structural, mechanical and tribological properties of molybdenum-copper nanocomposite films 'doped' with small amounts of nitrogen, which contain either no nitride phase (i.e. the nitrogen is held ...
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

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 ...
Composite DLC-metal/metal-carbide coatings produced by electron enhanced unbalanced magnetron sputtering
(1997)
Composite coatings consisting of metal containing diamond like carbons were produced by unbalanced magnetron sputtering in a closed field magnetic configuration. Targets of Pta and W were poisoned with acetylene during the ...
Deposition and characterisation of TiAlBN coatings produced by direct electron-beam evaporation of Ti and Ti-Al-B-N material from a twin crucible source
(1999)
TiAlBN coatings were synthesised by evaporating Ti and hot isostatically pressed TiAl0.68B3.67N2.44 material from a twin crucible source in an Ar plasma at 450°C. A combination of optical emission spectroscopy and partial ...
