    • Atom Probe Tomography investigations on grain boundary segregation in polycrystalline Ti(C,N) and Zr(C,N) CVD coatings 

      El Azhari, Idriss; Barrirero, Jenifer; García, José; Soldera, Flavio; Llanes Pitarch, Luis Miguel; Mücklich, F. (2019-03-15)
      Article
      Open Access
      Atom Probe Tomography (APT) was used to obtain a direct evidence of chlor segregation and cobalt diffusion at the grain boundaries (GBs) of polycrystalline coatings deposited by moderate temperature chemical vapor deposition ...
    • Chemical segregation in a 12Ce-ZrO2/3Y-ZrO2 ceramic composite 

      Roa Rovira, Joan Josep; Aboulfadl, Hisham; Barrirero, Jenifer; Turón Viñas, Miquel; Mücklich, Frank; Anglada Gomila, Marcos Juan (2017-10-01)

      In restorative dentistry, 3Y-ZrO2 ceramics are widely accepted for fabricating dental crowns, bridges and implants due to their good biocompatibility, excellent mechanical properties and high aesthetics potential. However, ...
    • Growth and thermal stability of TiN/ZrAlN: Effect of internal interfaces 

      Yalamanchili, Kumar; Wang, Fei; Aboulfadl, Hisham; Barrirero, Jenifer; Rogstrom, Lina; Jiménez Piqué, Emilio; Mücklich, F.; Tasnadi, Ferenc; Odén, Magnus; Ghafoor, N (2016-12-01)
      Article
      Open Access
      Wear resistant hard films comprised of cubic transition metal nitride (c-TMN) and metastable c-AlN with coherent interfaces have a confined operating envelope governed by the limited thermal stability of metastable phases. ...
