Corrosion mechanism suggested based on electrochemical analysis and SVET for uncoated tinplate and post coated with a hybrid film
Kunst, Sandra Raquel; Beltrami, Lílian Vanessa Rossa; Boniatti, Rosiana; Quevedo Reyes, Marcela Citlalim; Bastos, António Alexandre Cunha; Oliveira, Cláudia Trindade; Ferreira, Mário Guerreiro Silva; Menezes, Tiago Lemos; Malfatti, Célia de Fraga (2017) [Artigo de periódico]The tinplate, used in the packaging sector and formed from a metal substrate, comprises a steel base which has undergone a surface treatment to produce a thin layer of FeSn2, a tin layer and an oxide tin layer. Currently, ... -
Effect of concentrations of plasticizers on the sol-gel properties developed from alkoxides precursors
Kunst, Sandra Raquel; Longhi, Marielen; Beltrami, Lílian Vanessa Rossa; Zini, Lucas Pandolphi; Boniatti, Rosiana; Cardoso, Henrique Ribeiro Piaggio; Ortega Vega, Maria Rita; Malfatti, Célia de Fraga (2017) [Artigo de periódico]Coatings developed through sol-gel method is presented as an interesting replacement to chromium coating. Sol-gel method present advantages as high purity and excellent distribution of the components. The objective of this ... -
Electrochemical and mechanical behavior of UV curing paint on hybrid films modified with polyethyleneglycol plasticizer applied on tinplate
Marcolin, Patrícia; Beltrami, Lílian Vanessa Rossa; Boniatti, Rosiana; Salvador, Débora Guerra; Quevedo Reyes, Marcela Citlalim; Bastos, António Alexandre Cunha; Ferreira, Mário Guerreiro Silva; Malfatti, Célia de Fraga; Kunst, Sandra Raquel (2017) [Artigo de periódico]The objective of this work is to coat tinplate with a hybrid film obtained from a sol-gel process constituted by the alkoxide precursor tetraethoxysilane (TEOS) and 3-trimethoxysilylpropyl methacrylate (TMSM), with the ... -
Obtainment and characterization of a silicon alkoxides-based coating applied to a substrate of stainless steel 316L for use in biomaterials
Longhi, Marielen; Boniatti, Rosiana; Kunst, Sandra Raquel; Santos, Venina dos; Ferreira, Jane Zoppas (2019) [Artigo de periódico]The silicon alkoxides-based coating is an alternative to control the release of cytotoxic ions through metal implants. This study evaluated the influence of the number of layers of a hybrid coating on the surface of ...
