Machine Learning Accelerated Design and Discovery of Rare-earth Phosphates as Next Generation Environmental Barrier Coatings
Researchers from Rensselaer Polytechnic Institute synthesized single phase multiple component rare-earth phosphate as potential environmental barrier coatings of structure materials for space and aerospace application. Thermo-mechanical properties of the multicomponent phosphates are measured. The resistance of the multicomponent phosphates against molten glass attack was investigated at different temperature and durations. Multicomponent phosphates display comparable coefficient of thermal expansion, but significantly lower thermal conductivity as compared with single component counterparts, implying immense potentials as environmental barrier coating.
