| Abstract Scope |
Current fusion reactor designs, like magnetic confinement fusion, inertial confinement fusion, or stellarator concepts assume a strong temperature gradient from the armor material on the plasma facing component to the structural material of the fusion reactor. Designing those gradients has been tried directly or with interlayer materials using field assisted sintering technology or plasma spraying in the past. However, the formation of potential intermetallic phases and varying coefficients of thermal expansion and mechanical properties of the structural and armor material can lead to early failure of components under high heat fluxes and transients. Here, thermodynamic simulations and different additive manufacturing methods like electron beam melting, laser powder bed fusion, and direct energy deposition of gradient interfaces were combined to develop a first of its kind tailored interface for fusion reactor components for application temperatures between 600 and 1100 °C. Comprehensive testing of the microstructure was performed to evaluate component performance. |
