Degradation of Thermal-Barrier Coatings at Very High ...

A ceramic thermal-barrier coating needs to be refractory and chemically inert, and to have low thermal conductivity. However, it also needs to possess a high thermal expansion coefficient of ~11 × 10 −6 K −1, to match the nickel-base superalloy substrate. The latter specification has focused attention on ZrO 2.
