Comportamiento a fatiga térmica de la capa de anclaje de nuevas barreras térmicas cerámicas obtenidas mediante proyección por plasma atmosférico
Carpio Cobo, Pablo; Salvador Moya, María Dolores; Borrell, A.; Sánchez-Vilches, Enrique Universidad Pedágogica y Tecnológica de Colombia (UPTC) (2016-05)The development of new ceramic materials to protect the metallic components against corrosion and oxidation at high temperature, also known as thermal barriers coating (TBC), is of a great interest topic for many industrial ... -
Correlation of thermal conductivity of suspension plasma sprayed yttria stabilized zirconia coatings with some microstructural effects
Carpio Cobo, Pablo; Blochet, Quentin; Pateyron, Bernard; Pawłowski, L.; Salvador, M. D.; Borrell, A.; Sánchez-Vilches, Enrique 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 ... -
Effect of particle size distribution of suspension feedstock on the microstructure and mechanical properties of suspension plasma spraying YSZ coatings
Carpio Cobo, Pablo; Bannier, Emilie; Salvador Moya, María Dolores; Borrell, A.; Moreno, Rodrigo; Sánchez-Vilches, Enrique Elsevier (2015-04)In this work, aqueous suspension feedstocks with different particle size distribution from submicron- and nano-sized YSZ powders were prepared. A previous colloidal characterisation allowed concentrated suspensions (~ 40 ... -
Impact of Feedstock Nature on Thermal Conductivity of YSZ Thermal Barrier Coatings Obtained by Plasma Spraying
Carpio Cobo, Pablo; Salvador Moya, María Dolores; Benavente, Rut; Miranda, M.; Borrell, A.; Sánchez-Vilches, Enrique Göller Verlag GmbH (2016-09)Yttria-stabilized zirconia (YSZ) coatings with low thermal conductivity were obtained using three different particle size distributions as starting powder: nano-, submicron- and bimodal submicron/nano-sized particles. On ... -

D.; Sánchez-Vilches, Enrique Elsevier (2014-07)En el presente trabajo se ha estudiado la influencia de cada uno de los parámetros de la proyección térmica por plasma atmosférico (atmospheric plasma spraying, APS) en la deposición de dos polvos comerciales de YSZ, uno ... -
Investigation of deformation behavior and fracture of ceramic coatings by the acoustic emission method
Klyatskina, Elizabeta; Salvador Moya, María Dolores; Segovia López, Francisco; Carpio Cobo, Pablo; Borrell, A.; Sánchez-Vilches, Enrique; Stolyarov, V. V. Springer Verlag (2017-03)The use of protective coatings on components of machines and mechanisms provides the greatest economic benefit at the lowest additional cost. Plasma spraying is one of the most productive, technologically advanced, and ... -
Microstructure and mechanical properties of plasma spraying coatings from YSZ feedstocks comprising nano-and submicron-sized particles
Carpio Cobo, Pablo; Borrell, A.; Salvador Moya, María Dolores; Gómez, Andrés; Martínez, Eduardo; Sánchez-Vilches, Enrique Elsevier (2015-04)Atmospheric plasma spraying (APS) is an attractive technique to obtain nanostructured coatings due to its versatility, simplicity and relatively low cost. However, nanoparticles cannot be fed into the plasma using conventional ... -
