Aluminum protection by using green zirconium oxide layer and organic coating: An efficient and adherent dual system
Bonamigo Moreira, Vitor; Meneguzzi, Alvaro; Jiménez Piqué, Emilio; Alemán Llansó, Carlos; Armelín Diggroc, Elaine Aparecida (2021-09-01)
Article
Accés obertIn 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 obertThe 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 obertHerein, 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
Canales Gabriel, Manel; Torras Costa, Juan; Fabregat Jové, Georgina; Meneguzzi, Alvaro; Alemán Llansó, Carlos (2014-09-19)
Article
Accés restringit per política de l'editorialThe polaronic and bipolaronic forms of polyaniline emeraldine salt (PAni-ES) in the amorphous solid state have been simulated using classical molecular dynamics (MD) and hybrid quantum mechanical/molecular mechanical-molecular ... -
Smart paint for anodic protection of steel
Silva, Rodrigo Sanchonete; Alemán Llansó, Carlos; Ferreira, Carlos Arthur; Armelín Diggroc, Elaine Aparecida; Ferreira, Jane Zoppas; Meneguzzi, Alvaro (2015-01-01)
Article
Accés obertIn order to overcome the difficulties associated to the solubility and mechanical integrity of polyaniline (PAni) films, in this work we develop a binder by mixing PAni in the oxidized and undoped state (emeraldine base ... -
Spectroscopy investigations reveal unprecedented details in the corrosion of AISI 1012 UPN profiles installed in a modernist building of beginning of 20th century
Iribarren Laco, José Ignacio; Liesa Mestres, Francisco; Meneguzzi, Alvaro; Alemán Llansó, Carlos; Armelín Diggroc, Elaine Aparecida (2020-03-01)
Article
Accés obertn the present work, the corrosion affectation of an artistic and historical building, declared UNESCO World Heritage Site and constructed with AISI 1012 UPN profiles, was investigated. Micro-Raman and microscopy approaches ...
