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 ...
Kinetic study of the thermal decomposition process of calcite particles in air and CO2 atmosphere
(Elsevier, 2013-05)
The thermal decomposition process of calcite particles (0.45–3.60 mm average diameter), made up of porous agglomerates of very small CaCO3 microcrystals, was studied in the 975–1216 K temperature range. The experiments ...
Modeling of Drying Curves of Silica Nanofluid Droplets Dried in an Acoustic Levitator Using the Reaction Engineering Approach (REA) Model
(Taylor & Francis, 2013)
The use of nanoparticles has become of great interest in different industrial applications. The spray drying of nanofluids forms nanostructured grains, preserving the nanoparticle properties. In this work, individual ...
Influence of the feedstock characteristics on the microstructure and properties of Al2O3–TiO2 plasma-sprayed coatings
(Elsevier, 2013-04)
Atmospheric plasma spraying (APS) is an interesting technique to obtain nanostructured coatings due to its versatility, simplicity and relatively low cost. However, nanometric powders cannot be fed into the plume using ...
Study of colloidal behaviour and rheology of Al2O3-TiO2 nanosuspensions to obtain free-flowing spray-dried granules for atmospheric plasma spraying
(Elsevier, 2013-09)
This work deals with the dispersion and stabilisation of nanosized Al2O3 and TiO2 particles in aqueous medium. The dispersing conditions were studied as a function of pH, dispersant content, solid loading and ageing.

Correlation of thermal conductivity of suspension plasma sprayed yttria stabilized zirconia coatings with some microstructural effects
(Elsevier, 2013)
Yttria-stabilized zirconia (3YSZ) coatings were successfully obtained by suspension plasma spraying. The coatings present generally two-zones-microstructure comprising nanostructured zones contributed by unmolten, partially ...
Interaction of the chromium–iron black pigment with porcelanised stoneware
(Elsevier, 2013-09)
A study has been undertaken on the interaction between the (Fe,Cr)2O3 black pigment and an industrial porcelanised stoneware composition at its firing temperature. The results indicate that the glassy phase that forms ...
Electrochemical Degradation of Reactive Black 5 using two-different reactor configuration
(Nature Research, 2020)
Novel Sb-doped SnO2 ceramic electrodes sintered at different temperatures, are applied to the degradation of Reactive Black 5 in both divided and undivided electrochemical reactors. In the undivided reactor the discoloration ...

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, ...
