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

Rebholz, Claus; Leyland, A.; Matthews, A. (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 ...

Doping and alloying trends in new thermoelectric materials

Loo, S.; Lal, S.; Kyratsi, Theodora; Chung, D. Y.; Hsu, K. F.; Kanatzidis, M. G.; Hogan, T. P. (Affiliation: Dept. of Elec. and Comp. Engineering, Michigan State University, East Lansing, MI, United StatesCorrespondence Address: Loo, S.Dept. of Elec. and Comp. Engineering, Michigan State University, East Lansing, MI, United States, 2002)

New thermoelectric bulk materials such as CsBi4Te6 have shown superior properties to traditional materials, however, optimal performance requires continuing investigations of doping and alloying trends. A recently modified ...

The effect of boron additions on the tribological behaviour of TiN coatings produced by electron-beam evaporative PVD

Rebholz, Claus; Leyland, A.; Larour, P.; Charitidis, C.; Logothetidis, S.; Matthews, A. (1999)

TiN coatings containing small amounts of boron were synthesized by electron beam evaporating a Ti-B alloy material from a single crucible source into a plasma comprising Ar or an Ar/N2 mixture at a substrate temperature ...

Hall effect in detwinned single crystals of YBa2(Cu1-xZnx)3O7-δ in the mixed state

Schegolev, A. I.; Giapintzakis, John; Manson, J. T.; Ginsberg, D. M.; Dumler, I. (1996)

The effect of zinc doping on the mixed-state Hall effect in detwinned single crystals of YBa2Cu3O7-δ has been studied. We observe a sign reveral of the Hall effect in crystals with a superconducting transition temperature ...

Structure, mechanical and tribological properties of nitrogen-containing chromium coatings prepared by reactive magnetron sputtering

Rebholz, Claus; Ziegele, H.; Leyland, A.; Matthews, A. (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 ...

Structure, mechanical and tribological properties of sputtered TiAlBN thin films

Rebholz, Claus; Schneider, J. M.; Voevodin, A. A.; Steinebrunner, J.; Charitidis, C.; Logothetidis, S.; Leyland, A.; Matthews, A. (1999)

TiAlBN films were produced by simultaneously sputtering from TiAl and TiB2 targets in Ar/N2 mixtures at a substrate temperature of 150 °C. The goal of this investigation was to study the influence of the nitrogen content ...

Wear behaviour of carbon-containing tungsten coatings prepared by reactive magnetron sputtering

Rebholz, Claus; Schneider, J. M.; Leyland, A.; Matthews, A. (1999)

W(1-x)C(x) coatings (with x being in the range of 0.05-0.19) were deposited by reactive magnetron sputtering on to AISI 316 stainless-steel substrates in order to study the influence of the carbon content on the tribological ...

X-Ray diffraction investigations of magnetron sputtered TiCN coatings

Schneider, J. M.; Voevodin, A.; Rebholz, Claus; Matthews, A.; Hogg, J. H. C.; Lewis, D. B.; Ives, M. (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 ...
