“…In the process of global production and life, metal corrosion often brings great harm and loss to all walks of life. [1][2][3] At present, there are many ways to curb or prevent metal corrosion. Among them, the more mature methods mostly adopt external or internal coatings, such as organic coatings, [4,5] inorganic coatings, [6,7] nanocoatings, [8,9] electrochemical protection, [10,11] and other new methods.…”

In this study, the rust conversion coating that acts directly on the surface of rust layer, was studied from the preparation of rust conversion agents gallic acid (GA), 2‐hydroxyphosphonyl acetic acid (HPAA), and their compound (GA/HPAA), rust conversion effect and anticorrosive mechanism. Results show that 1) when GA and HPAA were combined to form GA/HPAA with a mass ratio of 2:1, the strengthening effect of rust conversion was observed, and a more complete, dense, and smooth covering film was generated on the rust surface. In this case, the corrosion current of GA/HPAA was reduced to 4.10 × 10−7 A cm−2, while the GA was 2.35 × 10−6 A cm−2 and HPAA was 2.16 × 10−6 A cm−2. 2) The mechanism of rust conversion and corrosion resistance can be expressed as that the chelation reaction can occur between the rust and rust conversion agent, which can generate new coordination covalent bonds O–Fe–O, P–O–Fe, and C–Fe–O. In this case, they can firmly lock the rust and prevent it from spreading further. Meanwhile, a highly cross‐linked dense anticorrosion protective film can be formed. Due to the presence of these chelating products, they can act as obstacles, prolonging the diffusion path of corrosive medium and slowing down the interaction with the metal matrix.

KOrrosions-DAten-BAank) ist ein leicht an die individuellen Belange eines Anwenders anpaabares, benutzerfreundliches Informationssystem in Form einer Programm-Shell zur Erfassung, Sammlung, Dokumentation und Archivierung von Korrosionsdaten verschiedenster Bereiche. Es ermoglicht einen leichten und schnellen Zugriff auf die archivierten Daten und verfiigt iiber komfortable Recherchieroptionen sowie Benutzeroberflachen in drei Sprachen -Deutsch, Englisch, Franzosisch. Dariiberhinaus stehen dem Benutzer eine Reihe von Optionen zur Aufbereitung, Interpretation und Dokumentation der Ergebnisse einer Recherche zur Verfiigung. KODABA ist in den Sprachen FORTRAN, CLIPPER und C geschrieben und fiir den Einsatz auf IBM-kompatiblen Personalcomputern unter dem Betriebssystem MS-DOS konzipiert. KODABA ist somit ein hilfreiches Instrument fur alle, die sich mit Korrosionsproblemen befassen miissen.Corrosion and damage resulting from corrosion cause considerable safety risks and high costs. In order to avoid or limit these consequences the design engineer and the plant operator require information on when and how corrosion effects can occur. Access to such information should be simple and fast. This is provided by the corrosion data information system KODABA, a system designed for collecting, compiling and archiving of corrosion data from various fields. KODABA consists of a user-friendly program shell which is easily adaptable to the specific needs of a client. It enables an easy and fast access to the archived data and offers comfortable query options and a user surface in English, French or German. In addition, a number of options are available for the management, interpretation and documentation of the results of a query. KODABA is written in FORTRAN, CLTPPER and C programming languages and designed for use on an IBM compatible personal computer running under the MS-DOS operating system. It has proven to be a helpful tool for anyone who has to deal with corrosion problems.
