Abstract:

In Phase II, reported on here, we investigated multifunctional coatings for re-entry applications that combine highemissivity with ablation resistance. The microstructural evolution of ablated samarium-doped zirconium diboridesiliconcarbide was investigated to understand the formation of the c1-Sm0.2Zr0.8O1.9 SZO oxide layer and its constituent components. In collaboration with AFRL we also measured the emittance of different emissivity modifiers.
