“…A value of n=1 corresponds to a smooth surface, and therefore CPE should be substituted by an ideal capacitor C. n=0.5 suggests a diffusion response or a porous material, and 0.5<n<1 is associated with heterogeneous, rough or non-homogeneous current distribution, as can be observed in the sample F0P90 45,46 . The evolution of the middle frequency time constant (Figure 8) would then be related to a change of the composition and to a reinforcement of the native zinc oxide layer by the cerium oxides.…”

This study proposes a new pretreatment method that uses alkoxide precursors with a plasticizing agent; the purpose of this study is to improve the electrochemical and mechanical properties of a galvanized steel surface. Galvanized steel was covered with a hybrid film obtained from a sol that consisted of two alkoxide precursors, 3 -(trimethoxysilylpropyl) methacrylate (TMSM) and tetraethoxysilane (TEOS), with nitrate cerium in a concentration of 0.01 M and a polyethylene glycol (PEG) plasticizer. The hybrid coatings were obtained by dip-coating method with various concentrations of plasticizer (0, 20, 40 and 60 g.L -1 ). The hybrid films were analyzed by scanning electron microscopy (SEM), profilometry, contact angle measurements, a tribometer with the type-setting ball on the plate and electrochemical tests. The addition of the plasticizer into the hybrid films improves the corrosion resistance behavior compared to the sample without the plasticizer. The addition of 20 g.L -1 of plasticizer showed the best performance in the electrochemical tests. The mechanical behavior results indicated that higher PEG concentrations resulted in films with enhanced durability.

“…Contudo, existem problemas significativos relacionados com o uso de latas de folha de flandres para armazenamento de produtos alimentares, os quais podem apresentar comportamento corrosivo, levando a falhas de corrosão, perda da integridade do selante e problemas de descoloração do material metálico. Além disso, o estanho presente na embalagem pode ocasionar problemas de intoxicação alimentar [1]. Portanto, tratamentos superficiais estão sendo propostos para contornar estes problemas.…”

ResumoFilmes híbridos estão sendo utilizados como revestimentos de substratos metálicos para proteção contra corrosão. Este trabalho tem como objetivo verificar o comportamento corrosivo de filmes híbridos com diferentes concentrações de polietilenoglicol (PEG) sobre folhas de flandres pela técnica de varredura por eletrodo vibratório (SVET). Os resultados demonstraram que o aumento da concentração de polietilenoglicol ocasionou a formação de fissuras e delaminação do filme híbrido. As análises por SVET demonstraram a possibilidade de analisar a corrosão localizada em regiões com defeitos no filme e no substrato metálico. Palavras-chave: Filmes híbridos; Corrosão; SVET. CORROSION CHARACTERIZATION OF HYBRID FILMS BY SVET AbstractHybrid films have been used as coatings for metallic substrate for corrosion protection. The present work aims to verify the behavior of hybrid coatings with different concentrations of polyethylenoglycol on tinplate for corrosion technique of vibrating electrode (SVET). The results showed that increasing of the polyethylenoglycol concentration caused the formation of cracks and delamination of the hybrid film. The analysis by SVET demonstrated the possibility of analyzing the localized corrosion in zones with defects in film and metallic substrate.

The mechanical properties and corrosion resistance of SA508-4Ni-Cr-Mo low carbon alloy steel are elucidated using tensile testing, Charpy impact testing, fracture surface analysis and in-situ electrochemical noise (EN) technique. The metallographic structures are characterized by metallographic microscope combining with transmission electron microscope (TEM), and the fracture morphology is characterized by scanning electron microscope (SEM). The intercritical heat treatment (IHT) is introduced to heat the SA508-4 steel. The experimental observations reveal that the metallographic structure of SA508-4 steel is fine and uniform after different heat treatment, with martensite and lower bainite structures. The strength and toughness of SA508-4Ni-Cr-Mo are confirmed higher than that of SA508-3Mn-Ni-Mo steel used for reactor pressure vessels (RPV) at present. The IHT decreases the yield strength and toughness. EN results show that the noise resistance of SA508-4 steel decreased with the elevated temperature from 27 to 250°C, illustrating the passivity degradation of SA508-4 induced by the elevated temperature.
