Investigation of deformation behavior and fracture of ceramic coatings by the acoustic emission method
(Springer Verlag, 2017-03)
The use of protective coatings on components of machines and mechanisms provides the greatest economic benefit at the lowest additional cost. Plasma spraying is one of the most productive, technologically advanced, and ...
Thermal behaviour of multilayer and functionally-graded YSZ/Gd2Zr2O7 coatings
(Elsevier, 2017)
Zirconates with pyrochlore structure, such as Gd2Zr2O7, are new promising thermal barrier coatings because of their very low thermal conductivity and good chemical resistance against molten salts. However, their coefficient ...
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 ...
Preparation of feedstocks from nano/submicron-sized TiO2 particles to obtain photocatalytic coatings by atmospheric plasma spraying
(Elsevier, 2014-12)
Atmospheric plasma spraying (APS) has been proved useful in obtaining TiO2 coatings with effective photocatalytic activity. However, the influence of feedstock characteristics on photocatalytic activity has hardly been ...
Effect of TiO2 addition on the microstructure and nanomechanical properties of Al2O3 Suspension Plasma Sprayed coatings
(Elsevier, 2014-10)
Alumina–titania coatings are widely used in industry for wear, abrasion or corrosion protection components. Such layers are commonly deposited by atmospheric plasma spraying (APS) using powder as feedstock. In this study, ...
Atmospheric plasma spraying coatings from alumina–titania feedstock comprising bimodal particle size distributions
(Copyright © Elsevier, 2013)
In this work, Al2O3–13 wt% TiO2 submicron-nanostructured powders were deposited using atmospheric plasma spraying. The feedstocks were obtained by spray drying two starting suspensions of different solids content, prepared ...
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 ...
A study of the influence of TiO2 addition in Al2O3 coatings sprayed by suspension plasma spray
(Elsevier, 2015-09)
In this work, five different concentrations of a mixture of TiO2/Al2O3 nanopowders in an alcoholic suspension at 10wt.% solid content were sprayed by Suspension Plasma Spraying on steel discs. The influence of the presence ...
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 ...
Comportamiento a fatiga térmica de la capa de anclaje de nuevas barreras térmicas cerámicas obtenidas mediante proyección por plasma atmosférico
(Universidad Pedágogica y Tecnológica de Colombia (UPTC), 2016-05)
The development of new ceramic materials to protect the metallic components against corrosion and oxidation at
high temperature, also known as thermal barriers coating (TBC), is of a great interest topic for many industrial ...
