Dry-coating of magnetocaloric La(Fe,Si)13 — •Madhuri Wuppulluri, Snehajyoti Saha, Juliane Thielsch, Samuel Grasemann, and Anja Waske — IFW Dresden

La(Fe,Si)13 is a promising magnetocaloric material class with Curie transition near room temperature. However, forming regenerator beds for magnetocaloric cooling applications is challenging due to its poor mechanical strength. Pure elemental metal coating on La-Fe-Si results in higher mechanical strength, thermal conduction and reduces corrosion. Here dry coating of LaFeSi-based particles is presented and compared to that of ball milling. Magnetic and structural characterization of the coated powders is discussed.
