Manufacturing of Functional Sintered Parts with Inherently Stored Information and Integrated Status Monitoring

摘要

Inherently stored specific data in a component facilitates its identification, processing and reproduction during its lifecycle. The powder metallurgy offers great potentials to realize this concept by embedding foreign particles as data carriers in the part body prior to consolidation and sintering process. Furthermore monitoring of loading status or temperature of the sintered part during operation using embedded functional elements such as magneto-elastic stripes or temperature sensors is possible. This approach offers a solution for the lifetime prognosis of sintered parts. The research is focused on the manufacturing methods and the impact of embedded foreign materials on the mechanical properties of the part using numerical analysis. It is one of the main incentives of the Collaborative Research Centre 653 "Gentelligent Components in Their Lifecycle".
