      Restricted access - publisher's policy
      In this study, the influence of corrosion on the mechanical response and damage induced under Hertzian indentation is assessed for three cemented carbides with metallic binders of different chemical nature. Corrosion ...
    • Laser micro-patterning of dental zirconia: effects on microstructure and reliability 

      Roitero, Erica (Universitat Politècnica de Catalunya, 2018-02-22)
      Doctoral thesis
      Open Access
      Tetragonal polycrystalline zirconia stabilized with 3% mol of yttria (3Y-TZP) is a popular bioceramic, increasingly used for dental applications thanks to its good mechanical properties, biocompatibility and aesthetic ...
    • Low temperature degradation of laser patterned 3Y-TZP: enhancement of resistance after thermal treatment

      Article
      Restricted access - publisher's policy
      Ceria-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 ...
    • Mechanical reliability of dental grade zirconia after laser patterning 

      Roitero, Erica; Anglada Gomila, Marcos Juan; Mücklich, F.; Jiménez Piqué, Emilio (Elsevier, 2018-10-01)
      Article
      Open Access
      The aim of this work is to test the mechanical properties of dental zirconia surfaces patterned with Nd:YAG laser interference (¿¿=¿532¿nm and 10¿ns pulse). The laser treatment produces an alteration of the topography, ...
