Abstract: Adjustable nozzles, shutters, cover plates and other turbo engine ''hot parts'' (combustion chamber, diffuser, etc.) are subject to a number of wear factors-high temperature, thermal shock, corrosion, erosion-which can act simultaneously in complex manner. Dry friction due to the relative motion of the shutters and cover plates is also present. This paper underlines the properties of protective ceramic structures. Information on the behavior of the developed coatings, together with thermal testing results, will enable a more comprehensive evaluation of the protective solutions.
