(Universidad Francisco de Paula Santander, 2021-08-25)
Dentro de las técnicas de tratamiento de aguas y aires, existe la fotocatálisis o fotoelectrocatalisis, donde el principio físico es la interacción de la radiación con la materia, utilizándose la radiación UV proveniente ...
Optimization of the parameters for obtaining zirconiaalumina coatings, made by flame spraying from results of numerical simulation
(Journal of Physics: Conference Series, 2017-12-29)
The K-Sommerfeld values (K) and the melting percentage (% F) obtained by numerical simulation using the Jets et Poudres software were used to find the projection parameters of zirconia-alumina coatings by thermal spraying ...
Obtaining and characterization of nanostructured coatings of zirconiaalumina- ceria by thermal spray flame
(Journal of Physics: Conference Series, 2019-11-19)
Zirconia, alumina and ceria powders were agglomerated, by granulator disk, to be used as raw material in the manufacture of coatings on red clay substrates by flame spray. Three mixtures of different compositions were made ...
