| Abstract | Transpiration cooling technique is a reusable and high-efficiency thermal protection system (TPS), which is potential to improve the reusability and security of re-entry space vehicle. Relatively low density, high permeability and high porosity are general requirements for porous media of transpiration cooling systems. In this work, a new porous high entropy metal hexaboride (Y0.2Yb0.2Sm0.2Nd0.2Eu0.2)B-6 is designed and prepared by the in-situ reaction/partial sintering method. Two reaction routes are designed to synthesize (Y0.2Yb0.2Sm0.2Nd0.2Eu0.2)B-6, including boron thermal reduction and borocarbon thermal reduction. The as-prepared porous HE (Y0.2Yb0.2Sm0.2Nd0.2Eu0.2)B-6 ceramics possess homogeneous microstructure and exhibit low density, high porosity, high compressive strength and high permeability. The combination of these properties makes porous HE (Y0.2Yb0.2Sm0.2Nd0.2Eu0.2)B-6 promising as a candidate porous media for various transpiration cooling applications.
