Bioactive glass suspensions preparation for suspension plasma spraying
(Elsevier, 2016-06)
A bioactive glass was dry-milled and sieved in order to obtain powders with particle size finer than 63 μm. Two suspensions, with different particle size distribution (D50 = 8.3 μm and D50 = 2.2 μm), were subsequently ...
Bioactive glass coatings by suspension plasma spraying from glycoletherbased solvent feedstock
(Elsevier, 2017)
Bioactive glasses are emerging as a substitute of hydroxyapatite in the development of
bioactive coatings for biomedical applications. The deposition of these coatings is carried out
by a wide range of methods, being ...
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 ...
45S5 bioactive glass coatings by atmospheric plasma spraying obtained from feedstocks prepared by different routes
(Springer Verlag, 2014-12)
45S5 bioactive glass powders with the composition of 45 SiO2, 6 P2O5, 24.5 CaO and 24.5 wt% Na2O were melted and quenched in water to obtain a frit. The frit was milled using two different routes: dry milling followed by ...
Large scale synthesis of nanostructured zirconia-based compounds from freeze-dried precursors
(Elsevier, 2013)
Nanocrystalline zirconia powders have been obtained at the multigram scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous acetic solutions. This technique has equally made possible to ...
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 ...
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.

Dispersion of mixtures of submicrometer and nanometre sized titanias to obtain porous bodies
(Elsevier, 2013-12)
The stability and rheological behaviour of bimodal titania suspensions was studied. Bimodal mixtures were prepared by mixing nanosized TiO2 powders with an average primary size of ∼20–40 nm and surface area of ∼50 m2 g−1 ...
Application of plasma-sprayed TiO2 coatings for industrial (tannery) wastewater treatment
(Elsevier, 2015-12)
Fine-structured photocatalytic TiO2 coatings were deposited by atmospheric plasma spraying (APS) on austenitic stainless steel coupons. One commercial spray-dried nanostructured TiO2 powder and five spray-dried powders ...
