Dentro de la síntesis de óxidos, la obtención de nanopartículas se muestra como una alternativa atractiva a los métodos tradicionales ya que el aumento de superfície específica generado al disminuir el tamaño de grano, ...
La hidroxiapatita (HA) ha sido ampliamente estudiada y clínicamente probada debido a sus propiedades bioactivas. Al ser un material demasiado frágil para ser implantado en condiciones sometidas a carga, se suele aplicar ...
En el document final presentat com a tesi doctoral per a la obtenció del grau de doctor per a la Universitat de Barcelona s'hi inclouen els resultats tant en forma d'articles internacionals, així com en forma de memòria ...
Due to the current interest on intermetallic compounds (IMCs), specially for their use at high temperatures being capable to substitute superalloys and, for the lately improvement of their lack of ductility, this work ...
The nanoindentation or indenter testing technique (ITT) is a functional and fast technique that can give us a lot of information about the mechanical properties of different materials at nanometric scale, from soft to ...
Aquest estudi mostra els resultats experimentals obtinguts en analitzar el nivell de ferrita "delta" residual en condicions de velocitat de refredament per arc elèctric, així com els resultats de la determinació experimental ...
En la presente tesis doctoral se evalúa el potencial de algunos subproductos de magnesio empleados para la formulación de diferentes materiales de construcción y su utilización en diferentes soluciones constructivas. En ...
This thesis focuses on the use of Cold Gas Spray technology (CGS) to spray different nature powders onto light alloys with the aim of increasing their wear resistance. The growing industrial interest for costs reduction ...
Nowadays, arsenic is an important problem in water pollution. Non-ferrous metallurgical industries generate arsenic residues because the ores contain this mineral. The high technology improvement is increasing the demand ...
The main subject of this thesis is the fabrication of functional titanium dioxide coatings by means of Atmospheric Plasma Spray (APS) and Cold Gas Spray (CGS). Functional role may be understood as the capacity of TiO2 ...
Desde hace décadas se implantó el uso en la industria de recubrimientos biocompatibles de hidroxiapatita obtenidos mediante proyección plasma sobre prótesis metálicas. El objetivo de estos recubrimientos es mejorar el ...
The use of renewable heat decreases the consumption of fossil resources, although its usage is intermittent and usually does not match the demand. A proper thermal energy storage system design can eliminate this problem ...
Nowadays, researchers have spent considerable effort on the development of new materials, with new properties and characteristics, and new methods of synthesis, in order to meet the demands of a market that is constantly ...
The main subject of this PhD Thesis is the manufacturing of titanium dioxide multifunctional coatings by means of two spraying technologies: Cold Gas Spray (CGS) and Atmospheric Plasma Spray (APS). The characteristics of ...
