Progress in mechanical and physical properties of high-temperature coating materials

The important applications of high-temperature coatings significantly extend the scopes of superalloys. For the gas turbines at the severe working environment, much attention can be paid on the reasonable estimation of the integrated coating-superalloy system, in particular, thermal mechanical fatigue and creep fatigue. It is evidently revolved into the related physical, chemical and mechanical performances of the high-temperature coating materials. In this paper, the physical and mechanical properties of high-temperature coating materials were reviewed and the interface behavior between coating and superalloys was also explored in the near future.
