The first part of this work evaluates the influence of the cure conditions on the preparation of 3-aminopropyl trimethoxysilane (APS) and the corrosion inhibitor 5-amino-1,3,4-thiadiazole-2-thiol (AMT) multilayered films onto AISI 1020 carbon steel. The steel samples were pretreated in a 10−2 mol L−1 AMT solution for 3 h, immersed twice in a 5% v/v APS solution, and heat-treated at different temperatures and curing times. Regardless of the curing conditions used, electrochemical impedance spectr...

Abstract Following on the results presented in the first part of this study, the focus of attention now shifts to the influence of different deposition sequences and heat treatment temperatures on the production of multilayered conversion coatings of silica and boehmite on 1020 carbon steel, aiming the improvement of the anticorrosive performance of alumina coatings in a saline medium. Thus, conversion coatings composed by different deposition sequences of two xerogel films (boehmite/silica and ...

Os problemas relacionados a corrosao sao frequentes, podendo ocorrer nas mais variadas areas, tais como, nas industrias quimica, petroquimica, naval, de construcao civil e automobilistica, dentre outros setores produtivos. Portanto, metodos para prevenir a corrosao devem ser empregados para evitar a perda de materiais e o uso de revestimentos metalicos tem servido bastante a este proposito. A producao de revestimentos metalicos permite modificar a superficie do substrato levando a formacao de um...

Abstract Boehmite and silica conversion coatings were produced by sol-gel dip coating and heat-treated at different temperatures to improve the anticorrosive performance of alumina film deposited on AISI 1020 carbon steel substrate. SEM and XRD were used to evaluate, respectively, the morphology and composition of the conversion coatings. After covering these conversion coatings with alumina film, the systems were characterized by electrochemical impedance spectroscopy. Although both silica and ...
