  • 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
    Restricted access - publisher's policy
    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 ...
