Fused Coatings for Plasma Facing Components in Fusion Reactors

Fusion energy has the ability to provide a greater source of energy with lower harmful byproducts than any energy producing device currently on the planet. In order to make the production of fusion energy more real, there is a genuine need for new and novel materials that will be able to handle the harsh plasma environment including high heat loads, sputtering, and radiation. MesoCoat proposes to develop a series of nano-/micro-composite coating materials to be applied to Plasma Facing Components using MesoCoat & apos;s high energy density fusion cladding process, CermaCladTM. The materials being explored include tungsten and molybdenum based coatings which will improve plasma performance and helium based cooling while minimizing thermal stresses and providing excellent corrosion resistance. Commercial Applications and other Benefits: The material system and process developed in this program will help advance the development of Fusion reactors, which will provide a new large and clean energy source to the world. Beyond the fusion energy applications these materials and the CermaClad process can be used in fission energy reactors, and in the chemical processing industries providing improved corrosion resistance and better mechanical properties at elevated temperatures
