    Melk, Latifa; Roa Rovira, Joan Josep; García Marro, Fernando; Antti, Marta-Lena; Milsom, Ben; Reece, Michel; Anglada Gomila, Marcos Juan (2015-03-01)
    Article
    Open Access
    Multi-walled carbon nanotubes (MWCNTs)/3 mol% yttria-doped tetragonal zirconia (3Y-TZP) composites were produced using spark plasma sintering (SPS) with MWCNT content ranging within 0-2 wt%. In the present paper, it was ...

    In the last decades there has been growing interest in developing ceramic materials with high fracture toughness (Klc) and strength for structural applications. In the specific case of 3 mol% yttria-doped tetragonal zirconia ...
  • Surface microstructural changes of spark plasma sintered zirconia after grinding and annealing 

    Melk, Latifa; Mouzon, Johanne; Turón Viñas, Miquel; Akhtar, Farid; Antti, Marta-lena; Anglada Gomila, Marcos Juan (2016-11-01)
    Article
    Open Access
    Spark plasma sintered zirconia (3Y-TZP) specimens have been produced of 140 nm 372 nm and 753 nm grain sizes by sintering at 1250 °C, 1450 °C and 1600 °C, respectively. The sintered zirconia specimens were grinded using a ...
  • The influence of unshielded small cracks in the fracture toughness of yttria and of ceria stabilised zirconia 

    Melk, Latifa; Turón Viñas, Miquel; Roa Rovira, Joan Josep; Antti, Marta-Lena; Anglada Gomila, Marcos Juan (Elsevier, 2016-01-01)
