CERAMIC MATERIAL FOR THERMAL BARRIER COATING AND MANUFACTURING METHOD THEREOF
The present disclosure provides a ceramic material for a thermal barrier coating and a manufacturing method thereof. A chemical composition of the ceramic material is LaYbZrCeO7. The ceramic material is manufactured by doping LaO1.5, YbO1.5 and CeO2 into ZrO2. A mole ratio of LaO1.5, YbO1.5, CeO2 and ZrO2 is 1:1:1:1. The manufactured ceramic material is in a composite phase structure mainly including a pyrochlore phase and a fluorite phase. The ceramic material according to the present disclosure can effectively inhibit corrosion penetration of molten CMAS in a high temperature environment, which reduces or avoids ceramic cracking and peeling. This better maintains microstructural integrity of the ceramic surface, thereby extending service life of ceramics.
