Composite ceramics thermal barrier coatings of yttria stabilized zirconia for aero engines
Abstract Composite ceramics thermal barrier coatings (TBCs) are widely used in the aero engines field due to their excellent thermal insulation, which improves the service life and durability of the inherent hot components. The most typical, successful and widely used TBCs material is yttria stabilized zirconia (YSZ) In this paper, fabrication methods, coating structures, materials, failure mechanism and major challenges of YSZ TBCs are introduced and reviewed. The research tendency is put forward as well. This review provides a good understanding of the YSZ TBCs and inspires researchers to discover versatile ideas to improve the TBCs systems.
