“…X‐ray photoelectron spectroscopy (XPS) analysis on the rust (Figure S3, Supporting Information) revealed an oxidation state of III for iron and no other metals were detected. X‐ray diffraction (XRD) (Figure S4, Supporting Information) performed on the rust detected a crystalline phase of β‐FeO(OH) (akaganeite) . These results suggest the etching process was initiated by GA coordinating Fe III ions from the rust layer.…”

The use of natural compounds for preparing hybrid molecular films-such as surface coatings made from metal-phenolic networks (MPNs)-is of interest in areas ranging from catalysis and separations to biomedicine. However, to date, the film growth of MPNs has been observed to proceed in discrete steps (≈10 nm per step) where the coordination-driven interfacial assembly ceases beyond a finite time (≈1 min). Here, it is demonstrated that the assembly process for MPNs can be modulated from discrete to continuous by utilizing solid-state reactants (i.e., rusted iron objects). Gallic acid etches iron from rust and produces chelate complexes in solution that continuously assemble at the interface of solid substrates dispersed in the system. The result is stable, continuous growth of MPN films. The presented double dynamic process-that is, etching and self-assembly-provides new insights into the chemistry of MPN assembly while enabling control over the MPN film thickness by simply varying the reaction time.

“…In contrast, rust converters can be directly applied to the corroded surfaces, react with iron oxides and generate new compounds that have a passivation effect on the steel to protect the surfaces against possible further attacks (17)(18)(19). Residual rust coatings containing the rust converter without the need of pre-derusting has the advantages over the common anticorrosive coatings (20). Nowadays, most studies regarding residual rust coatings are based on tannic and phosphoric acids (21,22).…”

“…These species have also been reported for steel samples corroded under different atmospheric conditions. [28][29][30][31][32][33][34][35] Magnetite and maghemite present a similar crystalline structure 36 which makes it difficult to distinguish them by XRD, as previously stated by different authors. 34,37 The data presented allows one concluding similar profiles for samples obtained after different periods of exposure.…”

“…34,37 The data presented allows one concluding similar profiles for samples obtained after different periods of exposure. It is outstanding the absence of akaganeite (β-FeOOH) as a corrosion product, since several authors associate the formation of this phase with the presence of high chloride concentrations, [28][29][30][31][32][33][34][35][36][37] which is very common in marine environments. A possible explanation could be the experimental characterization technique employed, since Rémazeilles and Refait have reported that akaganeite could be detected by FTIR but not by XRD and Raman spectroscopy.…”

In this work, the deposition rate of two of the main ions involved in the corrosion caused by marine aerosol (SO 4 2and Cl -) were monitored for three years, by using three different collection methods: alkaline sulphation plate, wet candle and dry plate (ASP, WC and DP). The deposition rate of Cland SO 4 2evidenced significant differences depending on the method, with higher suitability of ASP to simultaneously collect both ions. The use of this method also provided a higher correlation coefficient of the corrosion rate of steel with the ions deposition. These results have a direct impact in the standard ISO 9225 (2012).
