Current-Activated Reactive Ultrafast Joining (CARUJ) of High Temperature Materials

closed

The high-temperature systems and components for the next generation CSP require new materials such as cermets, ceramics, refractory alloys, and composites that must be integrated with similar material types and/or with metal alloys. The joining of similar and dissimilar materials is extremely challenging. This project proposing is developing a current-activated reactive ultrafast joining (CARUJ) technology, which uses thin layers of precursor materials between the two parts and pass electric current through it. The team will perform various characterizations to evaluate the efficacy of the joints. Successful development and testing of CARUJ will benefit the deployment of next-generation thermal systems.
