| Abstract Scope |
Reliable ceramic-metal interfaces need further development for structural and functional components operating in extreme environments. This research investigates the initial stages of joining silicon carbide (SiC) to refractory metals such as molybdenum (Mo) via metal deposition. The research aims to investigate interfacial reactions and phase formation/evolution during annealing of Mo-SiC systems, and to correlate these with the mechanical properties of the film and interface.
The research includes performing EBSD, TEM, and XRD analyses to assess the phases present at each annealing temperature, both within the film and near the interface. The research also involves performing nanoindentation (hardness and scratch tests) to evaluate interface and film strength.
This work presents basic methods for evaluating phase formation and evolution, as well as the mechanical behavior of this kind of interface with temperature. The results obtained will enable the development of ceramic-to-metal systems that function in harsh environmental conditions. |
