Article
Accés obertThe aim of this work is to generate micrometric linear patterns with different topography on dental grade zirconia by means of UV laser interference and to assess the quality of the produced surface, both in term of the ... -
Corrosion-induced changes on Hertzian contact damage in cemented carbides
Zheng, Yafeng; Fargas Ribas, Gemma; Lavigne, Olivier; Roitero, Erica; Llanes Pitarch, Luis Miguel (2020-11-01)
Article
Accés obertIn 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)
Tesi
Accés obertTetragonal 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 ... -

Roitero, Erica; Ochoa Vives, Manuel; Anglada Gomila, Marcos Juan; Mücklich, Frank; Jiménez Piqué, Emilio (Elsevier, 2018-04)
Article
Accés obertThe aim of this study is to characterize the resistance to low temperature degradation (LTD) of the surface of dental-grade zirconia (3Y-TZP) patterned with a Nd:YAG laser (532. nm harmonic and pulse duration of 10. ns) ... -
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 ... -
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
Accés obertThe 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, ... -
