International Conference on aerospace Materials(ICAM 2006)

作者： Boris A. Movchan Kostyantyn Yu.Yakovchuk International center for Electron Beam Technologies (ICEBT) of E.O.Paton Electric Welding Institute National Academy of Sciences of Ukraine 68 Gorky St. Kiev-150 03150 Ukraine International center for Electron Beam Technologies (ICEBT) of E.O.Paton Electric Welding Institute National Academy of Sciences of Ukraine 68 Gorky St. Kiev-150 03150 Ukraine

Electron beam technology (EB-PVD) and equipment for one-stage deposition of advanced graded protective coatings using a composite ceramic ingot for evaporation are described. This technology allows replacing the flat interface between coating layers by a graded transition zones and achieve of a high degree of reproducibility of the composition, structure and lifetime of the functionally graded coating in compare with traditional multi-stages technologies of protective coating deposition.A design of the composite ceramic ingot is considered, as well as the ability to regulate in a broad range the composition, structure and properties of all levels of the graded protective coating including transition zones and coating layers. Examples and variants of advanced graded protective coatings with their structures and properties are given (thermal barrier, hard erosion-resistant and damping coatings) for aerospace and gas-turbine industry application deposited by one-stage EB-PVD process. Total cost of one-stage EB-PVD deposition process at least 2 times less in compare with traditional technological processes of protective coating deposition due to using only one EB-PVD unit and elimination of multistage nature of process *** and productive electron-beam units designed and manufactured at ICEBT are considered.

关键词： electron beam evaporation and deposition (EB-PVD), graded protective coatings, gas turbine blades, composite ingot.
