Article
The corrosion protection mechanism of 2-mercaptobenzothiazole (2-MBT) and its potential synergistic effect with cerium chloride (CeCl3) for sustainability of the aerospace alloy AA 2024-T3 was investigated. The corrosion inhibitors 2-MBT and CeCl3 and their potential synergistic properties were assessed with image-assisted electrochemical noise, th...

The anticorrosion performance provided by new anodizing and sealing methods for the AA2024T3 aluminum alloy is discussed in this work. Two anti-corrosion post-anodizing treatments based on immersion in an ethanol solution containing 2-mercapto-benzothiazole (2-MBT) were applied. Both treatments consisted of the immersion of the anodized specimens i...
Article
In this work, novel two-shell structured inhibitor-loaded Poly(methacrylic acid)@cerium oxide (PMAA@CeO2) nanocontainers were synthesised and characterized. The purpose of the nanocontainers is to increase the corrosion protection provided by an epoxy coating applied to an aerospace alloy (AA 2024-T3). The (PMAA@CeO2) nanocontainers with diameters...

In this study, the effectiveness of 2-mercaptobenzothiazole (2-MBT), 8-hydroxyquinoline and benzotriazole as corrosion inhibitors for AA 2024-T3 aluminium alloy was evaluated. The corrosion behaviour in the presence of each compound was investigated by image-assisted electrochemical noise analysis, electrochemical impedance spectroscopy, potentiody...

In this work, the behavior of cerium, cobalt and manganese nitrates, and their mixtures as corrosion inhibitors for AA 2024-T3 aluminum alloy has been investigated by potentiodynamic polarization and electrochemical noise measurement. It was found that cerium nitrate provides the best inhibition performance, followed by cobalt nitrate, with mangane...

The measurement of current and potential noise during corrosion generally requires two electrodes, coupled by a zero resistance ammeter (ZRA), and a reference electrode. Statistical methods then enable estimation of the noise resistance, if the electrodes are identical. In this work, a resistor is used instead of a ZRA and, consequently, the electr...

Full-text available
In this work, an overview of recent developments in materials characterization and performance assessment methods applied to corrosion is given. It is shown that 3D techniques represent a powerful tool to gain fundamental information on the relationship between alloy microstructure and corrosion initiation and propagation. Subsequently, taking as a...

Purpose The purpose of this paper is to study the release of corrosion inhibitor from nanocontainers and to show that it can be released due to reaction with the substrate induced by corrosion. This is called self‐healing of corrosion. Raman spectroscopy was used to show that reaction after scratching of the surface and corrosion of the substrate....

Epoxy coatings containing TiO2 nanocontainers were applied on aluminium alloy (AA) 2024-T3 for corrosion protection. The nanocontainers were loaded with the corrosion inhibitor 8-hydroxyquinoline (8-HQ). Epoxy coatings were deposited via the dip-coating process. The morphology of the coatings was examined by scanning electron microscopy (SEM). The...

a b s t r a c t The development of new technology that prevents corrosion of aluminium alloys (AA) 2024-T3 was made. AA 2024-T3 panels were coated with two layers the first one consists of conductive polymers (CP) and the second one, on the top, is made of sol–gel coatings. Ceramic nanocontainers loaded with cor-rosion inhibitors were incorporated...

This study is focused on corrosion protection of magnesium alloy ZK10. The aim of the research was the production of a hybrid organic–inorganic coating that would be a combination of epoxy resin, organically modified silicates as well as conductive polymer. Furthermore, ceramic containers loaded with corrosion inhibitor were incorporated into the c...

a b s t r a c t Organically modified silicate (ORMOSIL)–epoxy coatings were formed on aluminium alloy 2024-T3 in order to protect the substrates from corrosion. Organic and inorganic compounds, all known for their cor-rosion inhibition ability, were incorporated into the polymer matrix for the improvement of the corrosion resistance. The ORMOSIL–ep...

a b s t r a c t The corrosion protection properties of polypyrrole (PPy) electrodeposited onto aluminium alloy 2024-T3 substrates were investigated as a function of the doping agent. We used camphor sulfonic acid (CSA), para toluene sulfonic acid (p-TSA), phenylphosphonic acid (PPA), oxalic acid (OA) and cerium nitrate salt (Ce(NO 3) 3) as doping a...
