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 ... -
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. ...
