Corrosion Inhibition at Scribed Locations in Coated AA2024-T3 by Cerium- and DMTD-Loaded Natural Silica Microparticles under Continuous Immersion and Wet/Dry Cyclic Exposure

Earlier studies on cerium-loaded naturally-occurring silica microparticles (i.e. diatomaceous earth) demonstrated the potential to efficiently protect small scratches in epoxy-coated AA2024-T3 panels during relatively short immersion times. The current work investigates the potential of such inhibitor-loaded microparticles to protect wide and deep scribes (up to 1 mm wide) in long-time…

Interpreting Electrochemical Noise and Monitoring Local Corrosion by Means of Highly Resolved Spatiotemporal Real-Time Optics

Real-time optical analysis is used to improve the interpretation of electrochemical noise signals (EN). The concept is presented for the case of AA2024-T3 under immersion in various NaCl concentrations. An in-house developed optical-electrochemical technique allowed for high spatiotemporal resolution and was used to visualize and quantify surface changes in parallel with…

Reducing subjectivity in EIS interpretation of corrosion and corrosion inhibition processes by in-situ optical analysis

An in-situ hyphenated optical and electrochemical method for the real-time study of corrosion and corrosion inhibition processes is presented and validated for the case of AA2024-T3 exposed to two NaCl concentrations and six inhibitors. During testing, 5 μm resolution optical images of the exposed surface are obtained in parallel to electrochemical…

Long‐term active corrosion protection of damaged Coated‐AA2024‐T3 by embedded electrospun inhibiting nanonetworks

In this work, a new concept is introduced for active corrosion protection at damaged sites aiming at overcoming existing limitations of currently proposed strategies based on dispersed inhibitor‐loaded nanocontainers in coatings. The underlying principle is based on the formation of low‐density and/or humidity responsive interconnected paths of inhibitor in the…

Cerium-loaded algae exoskeletons for active corrosion protection of coated AA2024-T3

The use of micron sized nanoporous diatom algae exoskeletons for inhibitor storage and sustained corrosion protection of coated aluminium structures upon damage is presented. In this concept the algae exoskeleton allows local inhibitor loading, limits the interaction between the cerium and the epoxy/amine coating and allows for diffusion-controlled release of…

Diatoms as natural carriers for controlled release for metal protection and coatings

The present invention relates to a coating and coating application comprising a natural carrier for controlled release of a compound, such as for metal protection, a product comprising said coating or coating application, a method of modifying a natural carrier for controlled release, and methods of forming said coating or…
