Hot Corrosion in Gas Turbines
DURING COMBUSTION in the gas turbine, sulfur from the fuel reacts with sodium chloride from ingested air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulfidation) attack. This is commonly referred to as “hot corrosion.” Sulfur in the fuel is gen...
متن کاملEFFECT OF NANO SiC ADDITIVE ON MCMB-SiC COMPOSITE FABRICATION VIA MOLTEN SILICON INFILTRATION
C-SiC composites with carbon-based mesocarbon microbeads (MCMB) preforms are new type of highpreformance and high-temperature structural materials for aerospace applications. In this study MCMB-SiC composites with high density (2.41 g.cm-3) and high bending strength (210 MPa,) was prepared by cold isostatic press of mixed mesophase carbon powder derived from mesophase pitch with different amoun...
متن کاملHot Corrosion Behavior of Functional Graded Material Thermal Barrier Coating (RESEARCH NOTE)
In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strength and the related failure mechanisms of a conventional TBC and a FGM TBC are i...
متن کاملHot Corrosion of Slag Line in Plaster of Tundish in Continuous Casting of Steel
Plasters are produced from a light refractory material, mainly MgO (M.P. 2800ºC), a binder, and a void forming substance for insulating purposes. Different oxides from the slag penetrate into these voi...
متن کاملبررسی خواص پوشش های سد حرارتی ,csz ,csz-(micro)al2o3 csz-(nano)al2o3 بر روی سوپر آلیاژ پایه نیکل (اینکنل-738) به روش پاشش پلاسما
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
