Thermal Barrier Coatings, High-Entropy Oxides, and Zirconia Ceramics
This community develops ceramic coatings and bulk materials designed to withstand extreme heat, oxidation, and corrosion, with a parallel focus on zirconia-based ceramics for dental restoration.
The research centers on yttria-stabilized zirconia (YSZ) and high-entropy oxide ceramics, applied primarily as thermal barrier coatings (TBCs) and environmental barrier coatings. Key methods include plasma spraying and laser processing, while performance is evaluated through thermal shock, hot corrosion, and CMAS corrosion testing. A significant portion of the work addresses the mechanical integrity of these systems, specifically bond strength, shear bond, and microstructural evolution under thermal cycling. The community also investigates the application of monolithic zirconia and lithium disilicate in dental crowns and restorative dentistry, focusing on CAD/CAM manufacturing and biological compatibility.
The largest share of the community's output is found in zirconium research, accounting for 10.3% of all zirconium research, and yttrium research, accounting for 11.6% of all yttrium research.
The community comprises 17,709 papers, published most frequently in Ceramics International, Surface and Coatings Technology, and the Journal of the American Ceramic Society.
Recent work continues to explore high-entropy oxide synthesis and their application as thermal barriers, alongside non-destructive evaluation of coating defects and the development of zirconia ceramics for dental applications.
