| Abstract Scope |
The Joining of ceramic matrix composites (CMCs) has been a longstanding issue observed in various high temperature and nuclear protection systems. Current solutions applied to these high temperature and nuclear concerns introduce impurity and CTE related shortcomings, which can ultimately diminish long-term and high temperature performance.
Processing by EW-CVD can yield a homogeneous joining solution while cutting back on power consumption marks, yielding dense joining sections. Given this EW-CVD is attractive for nuclear cladding and the fabrication of complex CMC geometries. The EW-CVD process can also be extended to the fabrication of various full freestanding CMCs too.
Overall, the results yielded by EW-CVD lead to the formation of dense products, a high degree of phase control, and improved infiltration times, compared to conventional CVD/CVI methodologies. In this presentation the processing conditions, and properties of EW-CVD products will be discussed in terms of both joining efforts and freestanding CMCs developments. |
