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 ...
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 ...
Electron spectroscopic studies of nanocomposite PVD TiAlBN coatings
(2002)
A range of TiAlBN coatings have been deposited by electron beam evaporation and the optimised composition exhibits a 150% improvement over single phase TiAlN coatings in drilling tests. The coatings have been analysed by ...
Nanostructural studies of PVD TiAlB coatings
(2006)
TiAlB coatings with different compositions were deposited by co-sputtering from TiAl and TiB2 targets onto AISI316 stainless steel substrates at a temperature of 170 °C. The stoichiometry and nanostructure have been studied ...
Synthesis and characterization of Cr-B-N coatings deposited by reactive arc evaporation
(2008)
Nanocomposite Cr-B-N coatings were deposited from CrB0.2 compound targets by reactive arc evaporation using an Ar/N2 discharge at 500 °C and -20 V substrate bias. Elastic recoil detection (ERDA), x-ray photoelectron ...
Nanostructure, mechanical and tribological properties of reactive magnetron sputtered TiCx coatings
(2008)
This study describes the correlation between microstructure, mechanical and tribological properties of TiCx coatings (with x being in the range of 0-1.4), deposited by reactive magnetron sputtering from a Ti target in ...
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 ...
Comparative tribology studies of hard ceramic and composite metal-DLC coatings in sliding friction conditions
(1995)
The design of anti-friction coatings able to perform well in different wear conditions without lubricants requires a combination of adequate hardness and toughness, good adhesion, a low friction coefficient and a low wear ...
