Corrosion-Erosion Resistant Coatings for Steam Turbine Rotor Blades
Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Russian
Abstract: Capabilities of atomic-ionic deposition of metal-carbon ion-plasma coatings are investigated and evaluated. The coatings are intended to protect from drop-impact erosion and corrosion at wet steam operating conditions. Corrosion-erosion- resistant Cr-C coatings having micro- and nanocrystalline structure were deposited on a pilot batch of rotor blades. The coated blades were transferred for full-scale service tests in the turbine K-200-130 LMZ, stages 24 and 28. The developed technology is environmentally safe.
Key words: steam turbines, blades, erosion, nanostructure coatings, technology AIS.
