Simulated current distribution around an electrolyte-wetted Mg-Al mixed compound (Al-rivet in a Mg-sheet).

The Corrosion and Surface Technology department (WZK), headed by Prof. Mikhail Zheludkevich, studies the corrosion mechanisms of different light-weight metallic systems with special focus on Mg alloys. The main goals of WZK are dedicated to development of new alloys with tailored corrosion resistance as well new corrosion protection concepts for Mg components or multi-material structures. A novel concept of flexible functionalization of coatings via introduction of active nanocontainers, which are able to store the active functional agents and release them on demand in the presence of suitable triggers, is followed.
The knowledge gained on the corrosion control of structural systems is transferred to the metallic bio-materials and potential battery application. The corrosion related phenomena are studied using the local electrochemical and analytical techniques at different scales being supported by the multi-scale modelling approaches.
