The high speed PVD process (HS‐PVD) combines gas phase coating synthesis with high deposition rates. The process has been demonstrated for high purity YSZ deposited as a chemically bonded top thermal barrier with columnar structure of EB‐PVD features. The process can manufacture EB‐PVD like coatings that match in regards to their TGO‐formation and columnar structure. Coatings with a columnar structure formed by individual columns of 1/4 of the diameter of a classical EB‐PVD type TBC have been deposited. These coatings have the potential to prove a significant reduction in thermal conductivity and in erosion performance.
