Design of corrosion resistant coatings targeted for versatile applications - COR_ID

Corrosion is unfavourable process with huge economic and environmental adverse effects. Improvement of corrosion resistance of aluminium and its alloys, especially under operating conditions in aeronautical, nautical and automobile industries, is a necessity due to restriction of chromate conversion coatings. In the proposed project we investigate organic corrosion inhibitors and hydrophobic agents in combination with hybrid coatings for various aluminium metal substrates.

The objective of the project is to design multifunctional coatings which would simultaneously act as high-quality corrosion inhibitors and offer additional properties like hydrophobicity. These coatings will be used also for less corrosion resistant Al alloys or secondary Al alloys by industrial partner Talum to improve the functional performance of some of their products.

Through the project the following results have been achieved:

• Potential candidates for (i) hydrophobic compounds and (ii) corrosion inhibitor compounds based on alkyl and perfluoroalkyl chains were synthesized and tested on aluminum alloys. The most efficient compounds have been verified.The most corrosion resistant hybrid matrix has been selected and tested in field marine environment.
• A “virtual laboratory” is being established to enable the construction of parameters used in larger-scale simulations, such as, semi-empirical based molecular-dynamics.
• Pilot device for large-scale testing is under construction.

The project goals are being realized through the ICME (Integrated Computational Materials Engineering) paradigm consisting of integration of three fundamental disciplines: multi-scale modeling, multi-scale chemical synthesis, and high-throughput electrochemical and corrosion experimental testing and verification.
