Active environmental friendly coatings for light metals based on a combination of nano- and micro-containers

General Information

The project is devoted to the development of novel environmental friendly active anti-corrosion coating systems for light metal structures (Mg, Al) used in automotive and aeronautical design. The present project approaches this issue from the side of synergistic inhibition integrated in protective coatings applied onto the metal substrates. The main idea is to find the environmental friendly synergistic inhibitive combinations, which can provide effective suppression of corrosion of light metals, also for galvanically coupled dissimilar joints. Controlled release of inhibitors is obtained by loading them into appropriate nano-containers. The essential step is the introduction of inhibiting compounds into the protective layers based on an multi-layer concept consisting of PEO (Plasma Electrolytic Oxidation) coating for promoting adhesion and providing macro-containers, additional or integrated primer layers and final polymer top coats. This approach is used because the loss of nano-containers to the environment should be minimized thus the containers are added into the open pores of PEO coatings creating a "container in container" solution.
The achievement of these goals is not possible without extensive support of multi-scale modelling approaches on different stages of development process from inhibitor selection to the final design of the protective system and testing of the release of the inhibitors from the coatings. Molecular modelling approaches will be utilized in the case of inhibitor interaction with metallic, inorganic or polymer interfaces and selection of environmental friendly inhibitors.
