Glass–ceramics as oxidation resistant bond coat in thermal barrier coating system

Microstructure stabilization of a novel glass/YSZ composite coating material by adding alumina particles

“…Besides the traditional metallic coatings, e.g., aluminide and MCrAlY (M=Ni, Co, or their combinations) systems, inert oxide coatings, e.g., ceramic [4][5][6], glass-based [7][8][9][10][11][12][13][14] and glass-ceramic based composites [15][16][17][18][19][20], turn out to be effective alternatives due to their chemical stability at high temperatures. Especially, glass and glass-ceramics can bond well to the metallic substrates with ease of fabrication under suitable conditions, which leads to their extensive applications as coatings and seals [7][8][9][10][11][12][13][14][15][16][17][18][19].…”

Crystallization Behavior of SiO2–Al2O3–ZnO–CaO Glass System at 1123–1273 K

“…More recently, it was demonstrated that glass–ceramics, prepared by controlling the crystallization of the parent glasses, could combine the generally superior properties of crystallite ceramics with the ease of processing of glasses. Glass–ceramics could offer the advantages of a higher mechanical strength and more refractory behavior than its glassy counterpart, coupled with the ability to tailor the CTE to match the substrates 9–16 …”

Recent developments in the preparation, characterization and applications of glass- and glass–ceramic-to-metal seals and coatings

“…Other high-temperature seals Thermal barrier coatings are required to protect Ni-based superalloy components in advanced gas turbine and diesel engines which operate at higher temperatures and with reduced air cooling relative to conventional engine components [121][122][123]. Recently reported coatings for these applications include those based on magnesium and zinc Fig.…”
