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 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 ... -
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, ... -
Hardness and Young's modulus distributions in atmospheric plasmas prayed WC–Co coatings using nanoindentation
Elsevier (2011-05-25)A statistical indentation analysis of WC–Co coatings obtained by atmospheric plasma spray (APS) with two secondary plasma gases, H2 and He, was investigated using an instrumented indentation technique with the aim of ... -
In-situ laser synthesis of Nd–Al–O coatings: the role of sublattice cations in eutectic formation
International Union of Crystallography (2015-02)Neodymium aluminate coatings have been prepared in-situ by the laser zone melting (LZM) method, using a CO2 SLAB-type laser emitting at 10.6 µm. Polycrystalline Al2O3 commercial plates have been used as substrates, and ... -
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 ...
