current position：Information and data>What is Thermal Barrier Coating?
The so-called thermal barrier coatings (TBCs) refers to a "laminated" metal composed of a metal buffer layer (or metal bonding layer) and a ceramic thermal protection functional coating with good heat resistance and thermal insulation. Ceramic composite coating system. The surface ceramic working layer is bonded to the superalloy substrate by means of a metallic bonding layer between the substrate and the ceramic layer. The intermediate transition layer has excellent high temperature resistance and oxidation resistance, and the thermal expansion coefficient is between the base metal and the surface ceramic layer, which can reduce the interface stress and improve the bonding strength, thermal shock resistance and working life of the coating.
