Sustainable Corrosion Protection Through Digitization

Corrosion—that is, the electro-chemical reaction of base metals with oxygen or other environmental components—causes high maintenance effort up to damage of the material. This leads not only to defective materials, but also to immense costs and resource requirements, triggering an urgent need for action. Currently no platform exists on which innovations along the production chains for the development of corrosion protection technologies are supported. VIPCOAT aims to change this situation: VIPCOAT stands for “Virtual Open Innovation Platform for Active Protective Coating Guided by Modelling and Optimization”. Together with partners from Germany, Belgium, Luxembourg, Norway, Portugal, Great Britain and the Netherlands, the Helmholtz-Zentrum Hereon set the project in motion. The Hereon’s newly founded Institute for Surface Science, under the direction of Prof. Mikhail Zheludkevich, is taking a central role. The project begins on May 1st, 2021, and is financed over four years.

“Our aim is to create an open innovation platform that can be used by the research, industrial, political and public sectors alike,” says Dr. Natalia Konchakova, project coordinator and scientist at the Hereon’s Institute of Surface Science. The approach facilitates an effective transfer of science and communication between all those involved. The platform is to serve as a database (for experimental, industry-relevant and modeling data), scientific infrastructure and simulation base at the same time. Machine learning and physics-based modeling are combined here to optimize industry-relevant material development processes. “VIPCOAT is designed to support industry in making the development of customized corrosion protection technologies not only faster and more economical, but mainly to also to make them more sustainable and environmentally friendly,” says Konchakova. “Finding the best recipe for the corrosion protection system isn’t easy. That’s why we would like support the industrial sector in the best possible way by providing models and the innovation platform.”

Help of materials modeling and simulations

The industry faces questions such as: How does the coating’s microstructure look? What happens on the nano-level when the coating has a defect? Which environmentally friendly additives can be used to make the surface protection systems more corrosion resistant? How do the corrosion protection layers behave under real conditions—that is, alternately in a wet and dry state? All of these and more other issues can be answered in the future with the help of materials modeling and simulations using the platform.

The aerospace and automobile industries, for example, have been using inhibiting compounds in the past, which are in the meantime no more fully in line with European health and safety regulations. Industry and academia are intensively working and progressing on replacement alternatives. This is precisely where VIPCOAT comes in: the development of environmentally friendlier alternatives is advanced through the modeling and optimization joined by the innovation platform.

Open innovation approach

“For the aerospace industry, digital transformation represents an important element and opportunity to overcome the current economic crisis and emerge even stronger. VIPCOAT provides valuable contribution to digital material design and prediction of aging resistance,” says Theodor Hack, expert on corrosion and corrosion protection at Airbus, Central Research and Technology.

“Subsequently, the platform will also be applicable to other industrial sectors, such as the automotive and maritime sectors, energy production infrastructures and to medical technology and civil engineering,” says Dr. Peter Klein, scientist at the Fraunhofer ITWM. The open innovation approach should thereby contribute to a decisive competitive advantage for the sectors and strengthen the technology transfer.

Within the framework of VIPCOAT, the two contributing German research establishments, Hereon and Fraunhofer ITWM, will expand their expertise in the area of protective coatings with corrosion inhibitors and anti-corrosion pigments, respectively, and will create models for material development and optimization. Here the focus lies in sustainable infrastructures for offshore wind energy turbines and green marine energy technologies. This is how VIPCOAT results should directly support the aims of the European Green Deal.

Consortium

In addition to the Helmholtz-Zentrum Hereon, the project’s consortium includes the following partners: Airbus Operations GmbH, Airbus Defence and Space GmbH, Akzo Nobel Car Refinishes BV, ELYSCA NV, Wkki Limited, Fraunhofer Institute for Industrial Mathematics ITWM, Smallmatek – Small Materials and Technologies, Norwegian University of Science and Technology, Luxembourg Institute of Science and Technology, SINTEF, Vrije Universiteit Brussels (VUB) and Delft University of Technology. Within the Horizon 2020 program, specifically for the area of “Nanotechnologies, Advanced Materials, Biotechnology, and Advanced Manufacturing and Processing” (NMBP), VIPCOAT is funded with a total of 5,519,625 Euros.
