Thermal response of ceramic components during electron beam brazing
In this work, high-energy electron beam brazing of a ceramic part is modeled numerically. The part considered consists of a ceramic cylinder and disk between which is sandwiched an annular washer of braze material. An electron beam impinges on the disk, melting the braze metal. The resulting coupled electron-photon and thermal transport equations are solved using Monte Carlo and finite element techniques respectively. Results indicate that increased electron beam current decreases the time required to melt the braze while increasing temperature gradients in the ceramic near the braze. Furnace brazing was also simulated and predicted results indicate increased processing times relative to electron beam brazing.
