Question

A superalloy gas turbine component was originally

designed to operate at temperatures up to 760°C and exhibited

a stress rupture life of 900 h under this operating condition. An

updated design calls for a thermal barrier coating to be added

to the same component to allow engine operation under the

same conditions, but with an increase in reliability. If an

increase in rupture life to 1800 h is desired, what temperature

differential between the inside and outside of the component

must be achieved by the addition of the TBC?
