Abstract: 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.

Abstract: A bolster beam is correspondingly connected to a connection base by means of a damping unit; the radial dimensions of an outer wall of an inner supporting member and an inner wall of an outer supporting member gradually decrease from one end to the other end in a vertical direction; one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one is connected to the bolster beam; when in use, the inner supporting member and the outer supporting member tend to be close to each other, and since surfaces, close to each other, of the two are configured to be tapered, the two can-not be relatively separated; when getting closer to each other, the inner supporting member and the outer supporting member produce a compression action on an intermediate buffer member, and the intermediate buffer member is elastically deformable.
