      Article
      Accés restringit per política de l'editorial
      Exposure to hot water vapour is shown to be useful for staining indentation crack profiles in doped zirconia polycrystals. This is illustrated here in 3Y-TZP with two different grain sizes, for which Vickers indentation ...

    • 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, ...

    • Spherical indentation of polycrystalline cubic boron nitride (PcBN): contact damage evolution with increasing load and microstructural effects 

      Gordon Pozuelo, Sandra; García Marro, Fernando; Rodríguez Suárez, Teresa; Roa Rovira, Joan Josep; Jiménez Piqué, Emilio; Llanes Pitarch, Luis Miguel (Elsevier, 2023-02)
      Article
      Accés obert
      The extremely severe conditions at which cutting tools are exposed in hard machining operations require tool materials with outstanding mechanical properties. Excellent combinations of high hardness and fracture toughness ...

    • 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 ...

    • Strengthening of Vickers indented 3Y-TZP by hydrothermal ageing 

      García Marro, Fernando; Anglada Gomila, Marcos Juan (Elsevier, 2012-02)
      Article
      Accés restringit per política de l'editorial
      The effect of hydrothermal ageing on indentation cracks has been determined in 3Y-TZP by measuring the flexure strength of indented specimens before and after ageing. A substantial increase in strength was observed after ...
