The role of Ce(III)-enriched zeolites on the corrosion protection of AA2024-T3

The present work demonstrates that the addition of Ce-enriched zeolite microparticles to hybrid sol–gel formulation confers protection to the coating. After two weeks of immersion the integrity of sol–gel film remains unchanged. These properties are due to the fact that the Ce(III) loaded zeolite microparticles are released in response to the adsorption of ionic species involved in the corrosion process of AA2...

Assessemnt of corrosion in offshore environment. Study in windfloat prototype :...

In December 2011 WindFloat prototype, a semi-submersible floating structure was successfully deployed off the coast of Aguçadoura, North Sea of Portugal. The 2 MW WindFloat platform is the first offshore wind turbine in open Atlantic waters and as a demonstration project it appears as great opportunity to assess metal corrosion and anticorrosive protection systems efficiency in offshore environment. This kind o...

FTIR, a powerful technique in organic coatings failure diagnosis

FTIR spectrometry (Fourier Transform Infrared) is an instrumental technique of analysis that presents significant advantages on the dispersive traditional system, such as the increase of the relation signal-noise, the capacity of getting absorption spectra of low energy and therefore, bands of absorption of weak intensity. This technique is widely used in the study of resin characterization and evaluation of po...
