Nicholls, A Mechanism for the Erosion of EB PVD TBCS, Materials Science Forum, Vols 369-372, 2001, pp. 531-338http://www.scientific.nethttps://dspace.lib.cranfield.ac.uk/handle/1826/843Since the introduction of electron beam (EB) physical vapour deposition (PVD) TBCs and their application to moving components in the hot gas stream, erosion has become a prime concern. This project has been involved in determining the erosion mechanism of EB PVD TBCs, in order to develop a computational erosion model. The unique columnar microstructure of the EB PVD TBCs precludes the use of the classical brittle erosion mechanisms. This meant that a thorough investigation into the erosion mechanism of the coatings was necessary before it would be possible to develop a model to predict material wastage.1947 bytes634325 bytestext/plainapplication/pdfenErosionThermal Barrier CoatingsModellingErosion MechanismsPostprint
