HIGH ENTROPY CERAMIC THERMAL BARRIER COATING

A high entropy ceramic (HEC) composition includes at least three different rare earth (RE) oxides and at least one of hafnium dioxide (HfO2) and zirconia oxide (ZrO2). The at least three different rare earth oxides being equimolar fractions. In one aspect, the high entropy ceramic (HEC) composition...

Beschreibung
Zusammenfassung:	A high entropy ceramic (HEC) composition includes at least three different rare earth (RE) oxides and at least one of hafnium dioxide (HfO2) and zirconia oxide (ZrO2). The at least three different rare earth oxides being equimolar fractions. In one aspect, the high entropy ceramic (HEC) composition can be used in a thermal barrier coating.
