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 ...
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 ...
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 ...
Structure and mechanical properties of low temperature magnetron sputtered nanocrystalline (nc-)Ti(N,C)/amorphous diamond like carbon (a-C:H) coatings
(2010)
This paper reports on the structure and mechanical properties of 2μm thick nanocomposite (nc-) Ti(N,C)/amorphous diamond like carbon (a-C:H) coatings deposited on 100Cr6 steel substrates, using low temperature ( 200°C) DC ...
Evaluating the microstructure and performance of nanocomposite PVD TiAlBN coatings
(2002)
Physical vapour deposition (PVD) TiAlBN coatings can exhibit excellent wear resistance, with optimised coating compositions demonstrating a 150% increase in lifetime compared to standard TiAlN coatings in wet-cutting drill ...
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 ...
A study of the nanostructure and hardness of electron beam evaporated TiAlBN Coatings
(2010)
TiAlBN coatings have been deposited by electron beam (EB) evaporation from a single TiAlBN material source onto AISI 316 stainless steel substrates at a temperature of 450°C and substrate bias of −100V. The stoichiometry ...
Growth and characterization of ceria thin films and Ce-doped γ - Al 2 O 3 nanowires using sol-gel techniques
(2010)
γ - Al 2 O 3 is a well known catalyst support. The addition of Ce to γ - Al 2 O 3 is known to beneficially retard the phase transformation of γ - Al 2 O 3 to α - Al 2 O 3 and stabilize the γ-pore structure. In this ...
Nanoporous activated carbon cloth as a versatile material for hydrogen adsorption, selective gas separation and electrochemical energy storage
(2017)
The efficient storage of energy combined with a minimum carbon footprint is still considered one of the major challenges towards the transition to a progressive, sustainable and environmental friendly society on a global ...
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 ...
