Abstract

Abstract: Detonation gun spraying (D-gun spraying) is believed to be a promising new spraying technology in thermal barrier coatings (TBCs) for application to aircraft turbines. This chapter focuses mainly on two issues of aircraft turbine applications. It discusses first the low thermal conductivity of the new type of D-gun sprayed YSZ top coating. The failure mechanism of thermal shock cycling aimed at improving the lifetime of D-gun sprayed TBCs is then described.
