Mechanical properties of double-layer and graded composite coatings of YSZ obtained by atmospheric plasma spraying
(Springer Verlag, 2016)
Double-layer and graded composite coatings of yttria-stabilized zirconia were sprayed on metallic substrates by atmospheric plasma spray. The coating architecture was built up by combining two different feedstocks: one ...
Effect of the initial particle size distribution on the properties of suspension plasma sprayed Al2O3-TiO2 coatings
(Elsevier, 2015-04)
Al2O3–TiO2 coatings have been deposited by atmospheric plasma spraying from agglomerated, nanostructured powders showing better properties than those of their conventional (microstructured) counterparts. These nanostructured ...
Synthesis and processing of nanocrystalline tungsten carbide: Towards cemented carbides with optimal mechanical properties
(Elsevier, 2011-01)
Nanocrystalline tungsten carbide has been obtained by reduction/carburization at low temperature from precursors obtained by freeze-drying of aqueous solutions. Nanocrystalline WC powders with a adequate content of carbon ...
Microstructure and photocatalytic activity of suspension plasma sprayed TiO2 coatings on steel and glass substrates
(Elsevier, 2011-10-25)
In this study, TiO2 coatings were deposited by suspension plasma spraying (SPS) from a commercial TiO2 nanoparticle suspension on two different substrates: a standard stainless steel and a Pyrex glass. Coatings were sprayed ...
Preparation and spray drying of Al2O3–TiO2 nanoparticle suspensions to obtain nanostructured coatings by APS
(Elsevier, 2010)
Al2O3–TiO2 coatings were deposited on austenitic stainless steel coupons from nanostructured powders by atmospheric plasma spraying (APS). Commercial suspensions of nanosized Al2O3 and TiO2 particles were used as starting ...
Molten salt attack on multilayer and functionally-graded YSZ coatings
(Elsevier, 2018-08-01)
Thermal barrier coatings have been extensively studied in the last years in order to increase the operational temperature of the current gas turbines as well as to improve the coating lifetime. Many coating characteristics ...
Impact of Feedstock Nature on Thermal Conductivity of YSZ Thermal Barrier Coatings Obtained by Plasma Spraying
(Göller Verlag GmbH, 2016-09)
Yttria-stabilized zirconia (YSZ) coatings with low thermal conductivity were obtained using three different particle size distributions as starting powder: nano-, submicron- and bimodal submicron/nano-sized particles. On ...
Effect of particle size distribution of suspension feedstock on the microstructure and mechanical properties of suspension plasma spraying YSZ coatings
(Elsevier, 2015-04)
In this work, aqueous suspension feedstocks with different particle size distribution from submicron- and nano-sized YSZ powders were prepared. A previous colloidal characterisation allowed concentrated suspensions (~ 40 ...
Study of erosion behaviour of conventional and nanostructured WC-12Co coatings sprayed by atmospheric plasma
(Trans Tech Publications, 2010)
Thermal sprayed WC-Co coatings are used extensively to enhance the wear resistance of a wide range of engineering components. In this paper, erosive resistance of plasma atmospheric sprayed WC-12Co coatings has been ...
Nanoindentation study of the mechanical and damage behaviour of suspension plasmasprayed TiO2 coatings
(Elsevier, 2012-01)
TiO2 coatings can be used as self-cleaning surfaces owing to their photocatalytic and hydrophilic properties. Suspension plasma spray (SPS) has proven to be a feasible and cheap technique for producing self-cleaning surfaces ...
