Study of the corrosion behaviour of Ni-Co-Mn-In Heusler — •Ulysse Rocabert, Lukas Pfeuffer, and Oliver Gutfleisch — Functional Materials Group, Department of Materials and Earth Sciences, Technische Universität Darmstadt, Alarich-Weiss-Straße 16, 64287 Darmstadt, Germany

Heusler materials are one of the promising material classes that are considered for their very useful magnetocaloric properties at room temperature. While their magnetic and mechanical properties have seen broad investigation, their electrochemical properties especially in aqueous environment remain largely unstudied. This study focuses on the characterization of such properties of Ni-Co-Mn-In alloys in different chemical environments and proposes a assessment on their implementation into refrigeration systems in comparison with LaFeSi-Mn alloys.
