Resumo: This study was aimed at coating galvanised steel with a hybrid film obtained from a sol consisting of silane precursors 3 - (trimetoxisililpropil) methacrylate (TMSPMA) and tetraethoxysilane (TEOS). The pH of the hydrolysed-silane solution was 1 and 3. The influence of adding corrosion inhibitor (i.e. 0.01M cerium nitrate) was evaluated for all samples. The hybrid films were deposited by dip-coating. The film was characterised scanning electron microscopy (SEM), profilometry, contact angle measurement, potentiodynamic polarisation and electrochemical impedance spectroscopy. The results showed that solution pH influenced hybrid film formation and final surface properties. Additionally, cerium nitrate as corrosion inhibitor addition enhances corrosion resistance of the films.

Se evaluó la influencia de la adición de un inhibidor de corrosión, en este caso, nitrato de cerio 0.01 M, para todas las muestras. La aplicación de los filmes híbridos se realizó por dip-coating y su caracterización se realizó por microscopía electrónica de barrido (SEM), perfilometría, medición del ángulo de contacto, polarización potenciodinámica y espectroscopía de impedancia electroquímica. Los resultados muestran que el pH de la solución influye en la formación de los filmes híbridos y en sus propiedades superficiales finales, además, la adición del nitrato de cerio como inhibidor de corrosión mejora su resistencia.application/pdfengIngeniería e investigación [recurso eletrônico].
