New alloys, magnet materials (corrosion)

Metallic glasses (amorphous alloys) and related nanostructured or glass-matrix composite materials provide a wide spectrum of tunable mechanical, physical and chemical properties which suggest them for a variety of structural or functional applications. Generally metallic glasses are considered as highly corrosion-resistant materials, but recent studies revealed that the choice of composition for achieving high glass-forming ability, structural fluctuations or mechanical loads are critical factors for their corrosion stability. Our focus is on fundamental studies of corrosion mechanisms for Zr-, Ti-, Fe- and Mg-based alloy systems. We exploit this expertise for developing the advanced electrochemical micromachining technique (ECMM) for metallic glasses.

Rare earth magnets like NdFeB or SmCo are the strongest permanent magnets and have found a broad range of applications. But their corrosion stability is a critical aspect determining their life-time. We have a long-term expertise in characterizing corrosion properties of those materials. This ranges from fundamental studies of the effect of materials parameters, e.g. microstructure and magnetization state, on principal corrosion mechanisms up to the development of specific test scenarios for industrial needs. This expertise is used for corrosion analysis of novel magnetic shape memory alloys or magnetocaloric alloys and for developing recycling strategies for rare earth containing magnetic materials. We work in close cooperation with the groups Alloy Design and Processing,  Structural Research, Magnetocaloric Materials.
