AMT/APS Multilayered Films as Adherence Promoters for Epoxy Coatings on Carbon Steel—Part I: Influence of Curing Conditions on Anticorrosive Properties of AMT/APS Films in Saline Medium

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...
