Chemical and nanoindentation study of diffusion during sintering of 12Ce-ZrO2/3Y-ZrO2 powder layers
Roa Rovira, Joan Josep; Turón Viñas, Miquel; Tovar Vargas, Daniela; Ledesma, J.; Anglada Gomila, Marcos Juan (2018-02-01)
Article
Accés restringit per política de l'editorialTetragonal zirconia polycrystals doped with 3% mol of yttria (3Y-ZrO2) exhibit excellent mechanical properties and biocompatibility. However, under humid environments, their surface structural integrity is degraded by aging ... -
Enhancement of mechanical properties of ceria-calcia stabilized zirconia by alumina reinforcement
Tovar Vargas, Daniela; Turon Viñas, Miquel; Anglada Gomila, Marcos Juan; Jiménez Piqué, Emilio (Elsevier, 2020-01-01)
Article
Accés obertZirconia ceramics stabilized using 10 mol% CeO2 and 1 mol% CaO were studied with the addition of small amounts of a-alumina. The elaboration process of five different compositions was done by wet mixing of powders using ... -
Low temperature degradation and mechanical properties of alumina reinforced ceria-zirconia by colloidal processing
Tovar Vargas, Daniela; Ferrari, B; Anglada Gomila, Marcos Juan; Jiménez Piqué, Emilio (Elsevier, 2021-02-02)
Article
Accés obert10Ce-TZP base composites with 2.5, 5, 10 and 15 wt% alumina were fabricated by colloidal processing from slurries with 41 vol% solid load in order to investigate the effects of alumina in the final composites aging and ... -
Mechanical properties of ceria-calcia stabilized zirconia ceramics with alumina additions
Tovar Vargas, Daniela; Roitero, Erica; Anglada Gomila, Marcos Juan; Jiménez Piqué, Emilio (Elsevier, 2021-09)
Article
Accés obertCeria-stabilized zirconia-based composites have been developed aiming to obtain ceramic materials with enhanced hardness, strength, fracture toughness, and resistance to low temperature degradation. These composites are ... -
Processing, microstructure and mechanical properties of ceria-stabilized zirconia-based ceramics co-doped with calcia and alumina
Tovar Vargas, Daniela (2021-07-20)
Tesi
Accés obertIn recent years, zirconia ceramics have been used in many applications. Some of them include tool forming due to its high strength and fracture toughness, thermal barrier coatings on turbines engines due to its low thermal ...
