    • Relationship between density and mechanical properties of spark plasma sintered zirconia ceramics 

      Kiran Chitapalli, Ravi; García Marro, Fernando; Mestra Rodríguez, Álvaro Miguel; Reece, Michel; Anglada Gomila, Marcos Juan (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Zirconia ceramics stabilized with 3 mol % Yttria were produced by spark-plasma sintering. Toughness, Vickers hardness, nanoindentation elastic modulus and Berkovich hardness were determined in terms of the final density ...

    • Sliding wear behaviour of surface nitrided zirconia 

      Valle Chiro, Jorge Antonio; Mestra Rodríguez, Álvaro Miguel; García Marro, Fernando; Anglada Gomila, Marcos Juan (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Tetragonal polycrystalline zirconia stabilised with 3% molar yttria (3Y-TZP) has found wide applications in orthopaedics and dentistry because of its excellent mechanical properties (flexural strength above 1000 MPa, ...

    • Stability of nanocrystalline spark plasma sintered 3Y-TZP 

      Kiran Chitapalli, Ravi; Mestra Rodríguez, Álvaro Miguel; García Marro, Fernando; Yan, Haixue; Reece, Michel; Anglada Gomila, Marcos Juan (2010)
      Article
      Accés obert
      Spark plasma sintered 3Y-TZP has been investigated with respect to hydrothermal ageing and grinding. The sintering was performed between the temperatures of 1,100 and 1,600 °C for a soaking time of 5 minutes and the resulting ...

    • Surface modification of 3Y-TZP with cerium oxide 

      García Marro, Fernando; Valle Chiro, Jorge Antonio; Mestra Rodríguez, Álvaro Miguel; Anglada Gomila, Marcos Juan (Elsevier, 2010-11)
      Article

    • Thermal stability in air of surface nitrided 3Y-TZP 

      Valle Chiro, Jorge Antonio; Mestra Rodríguez, Álvaro Miguel; Anglada Gomila, Marcos Juan (Elsevier, 2011-06)
      Article
      Accés restringit per política de l'editorial
      Surface nitriding can be optimised to protect 3Y-TZP against hydrothermal degradation and at the same time to keep the mechanical properties of the surface and the bulk unchanged. However, thermal stability is a concern ...

    • Tratamientos post-mecanizado para la mejora de la integridad mecánica de metales duros electroerosionados 

      Llanes Pitarch, Luis Miguel; Casas Aguirregomezcorta, Begoña; Torres Hernández, Yadir; Mestra Rodríguez, Álvaro Miguel (2013)

    • Wear damage mechanisms in 3Y-TZP ceramics 

      Hvizdos, Pavol; Mestra Rodríguez, Álvaro Miguel; Anglada Gomila, Marcos Juan (2008)
      Article
      Accés restringit per política de l'editorial
      Tribological behaviour of two 3Y-TZP materials (polycrystalline zirconia stabilized by 3% of yttria) with different heat treatments (i.e. different grain size) has been studied using ball-on-disc technique in dry conditions ...

    • Weibull characterization of the flexural strength of hydrothermally degraded 3Y-TZP zirconia 

      García Marro, Fernando; Mestra Rodríguez, Álvaro Miguel; Lamghari, Manal; Anglada Gomila, Marcos Juan (2010)
      Text en actes de congrés
      Accés obert
      The flexural strength of 3% mol yttria-stabilized tetragonal polycrystalline zirconia (3Y-TZP) with a ~0.30m grain size was studied under 4-point bending test. The material was evaluated both as received and after water ...
