Abstract

The manufacture and performance of yttria partially stabilized zirconia thermal barrier coatings (TBC) on superalloys and on a superalloy eutectic were investigated. The TBCs were generated by electron-beam physical vapor deposition (EB-PVD). Performance was studied in a hot gas burner rig. Failure modes result from individual stress distribution and microstructural evolution within the TBC. A controlled columnar structure within density-graded TBC is expected to enable the coating life to be prolonged.
