| Abstract Scope |
Novel magnetic applications often require materials combining high functional and structural properties. While most additive manufacturing techniques allow for increased design flexibility and complex shape components, their deployment is limited by high electrical losses and insufficient mechanical performance. Cold spray additive manufacturing (CSAM) allows high deposition rate fabrication of magnetic components without the need for assembly. Using tailored powder feedstocks, it is possible to build components with improved mechanical properties surpassing conventional and other additive manufacturing techniques. In this presentation, recent CSAM developments on the fabrication of high integrity anisotropic NdFeB magnets and iron based soft magnetic materials will be detailed. The link between the powder mix characteristics (size distribution, shape, composition, magnetic loading), the process parameters (gas temperature and pressure), and the final properties will be analyzed. More specifically, functional material properties were optimized in terms of magnetic and mechanical performance to demonstrate their potential for future applications. |
