      In this work, the use of ZrO2 nanocoating in aluminum substrates, generated by controlled electrochemical chronoamperometry in hexafluorozirconic acid solutions (H2ZrF6·5H2O), resulted in a lower porous films than that ...
    • Computational image analysis as an alternative tool for the evaluation of corrosion in salt spray test 

      Bonamigo Moreira, Vitor; Krummenauer, Alex; Ferreira, Jane Zoppas; Armelín Diggroc, Elaine Aparecida; Meneguzzi, Alvaro (2020-01-01)
      Article
      Accés obert
      The current standards for evaluating corrosion during salt spray tests rely on the visual analysis of the specimens, and this may be a limitation when higher resolution quantitative outputs are desired. In this ...
    • Green nanocoatings based on the deposition of zirconium oxide: the role of the substrate 

      Bonamigo Moreira, Vitor; Puiggalí Jou, Anna; Jiménez Piqué, Emilio; Armelín Diggroc, Elaine Aparecida; Alemán Llansó, Carlos; Meneguzzi, Alvaro (Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-23)
      Article
      Accés obert
      Herein, the influence of the substrate in the formation of zirconium oxide monolayer, from an aqueous hexafluorozirconic acid solution, by chemical conversion and by electro-assisted deposition, has been approached. The ...
    • Polyaniline emeraldine salt in the amorphous solid state: polaron versus bipolaron
