Resilient Self-Healing Materials For The Extreme Environment Of Space Electric Propulsion & Power

Abstract

The objective of this proposal is to develop new conducting metallic and dielectric ceramic materials, endowed with micro-engineered surfaces, that will enable revolutionary advances in EP & PP technologies. The research project will focus on two complementary areas: (1) the fundamental sciences of failure and degradation of micro-engineered materials operating in the far-from-equilibrium plasma, elec-tromagnetic and photon environments of these technologies; and (2) the strong coupling between material physics and plasma performance. The studies will couple to the development of advanced plasma facing materials with design of plasma devices and operational methodologies that encourage or enforce in-situ healing of these materials. Two broad classes of material surface architectures will be investigated: (1) densely-packed surfaces with layered and non-layered coverage of micro-pillars. (2) reticulated metal and ceramic foams, attached to solid substrates.
