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 ...

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 ...

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

Multilayer composite ceramic-metal-DLC coatings for sliding wear applications
(1996)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 ...

Partially yttria-stabilized zirconia coatings produced under plasma-assisted EBPVD with bipolar pulsed bias and under electron bombardment-assisted positive bias conditions
(1997)Previous research using radio frequency (rf) plasma-assisted electron beam (EB) PVD to deposit partially yttria-stabilized zirconia (PYSZ) thermal barrier coatings has shown the benefits of this method in terms of structure ...

Wear resistant composite coatings deposited by electron enhanced closed field unbalanced magnetron sputtering
(1995)There is presently considerable interest in wear resistant coatings produced using closed field unbalanced magnetron sputtering technology. For example, layered films of diamond-like carbon (DLC) with tungsten or titanium ...
