This book was released on 1992 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first-stage high-pressure turbine blades in RAAF T-56 engines have a rejection rate which is unacceptably high. It has been revealed (1) that the current coating, a conventional nickel aluminide, has a greater than 60% rejection rate after 2000 hours. Consequently, a trial programme was established to assess the benefits of five alternative protective coatings and to determine which coatings, if any, could withstand up to 3000 engine operating hours. A previous report demonstrated the potential of platinum and platinum/rhodium modified aluminides after 1500 hours of engine operation. This report, after approximately 2000 hours of service, supports the previous recommendations that the precious metal aluminides offer superior resistance to hot corrosion than the conventional aluminides and chromium-modified aluminides. The inability of the silicon-modified aluminide to form an evenly distributed coating over the entire blade renders it unsuitable ...

Download or read book Protective Coatings for Turbine Blades written by Y. Tamarin and published by ASM International. This book was released on 2002 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the problem of surface protection for aircraft engine turbine blades. It is based on the author's 30+ years of work on the development and application of coatings to protect against oxidation and hot corrosion. It describes and details a methodology for optimizing turbine blade surface protection. The distinctions of this book from other publications on this topic include: The performance of protective coatings is assessed and evaluated by the complex interconnections of their chemical and phase composition, structure, and physical-mechanical properties; The properties of overlay coatings are given for the wide range of compositions, including the possible coatings states after their production and long-term service; The principles for calculating the stresses and strains for coated turbine blades are reviewed.

Download or read book Rainbow Field Test of Coatings for Hot Corrosion Protection of Gas Turbine Blades and Vanes written by Mark Van Roode and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rainbow field test sponsored by the Electric Power Research Institute (EPRI) under contract RP2465-1 was performed to evaluate the comparative hot corrosion resistance of commercially available coatings for gas turbine blades and vanes. The 10,307-hr field test was carried out on a Solar Turbines Incorporated Centaur T-4000 gas turbine operating on a lower grade liquid fuel at the Favianca site of the Owens-Illinois, Inc. glass manufacturing facility in Valera, Venezuela. This paper reviews the results of an evaluation of the performance of three modified aluminides, three MCrAlY overlays, and one duplex NiCoCrAlY/ZrO2-2OY2O3 overlay applied as coatings to the first-stage MAR-M421 and IN-738LC rotor blades, Visual and metallographic examination and remnant coating thickness measurements established that the MCrAlY overlay coatings were generally more effective than a Cr-aluminide and two Pt-aluminides protecting the first-stage blades. Individual differences between the various coatings were established. A remnant coating thickness index (RCTI) was defined to express coating survival and protectiveness quantitatively. The results of blade airfoil temperature estimates were correlated with the hot corrosion morphology.

Book excerpt: A rainbow field test sponsored by the Electric Power Research Institute (EPRI) under contract RP 2465-1 was performed to evaluate the comparative hot corrosion resistance of commercially available coatings for gas turbine blades and vanes. A 10,307-hr field test was carried out on a Solar Centaur T-4000 gas turbine operating on a lower grade liquid fuel at the Owens-Illinois, Inc. glass manufacturing facility in Valera, Venezuela. This paper reviews the results of an evaluation of the performance of a simple aluminide, a Pt, Rh-aluminide and two MCrAlY (M = Co, NiCo) overlays applied to the first stage FSX-414 vanes. As found for blade coatings, on the basis of visual and metallographic examination, and remnant coating thickness measurements, it was established that the MCrAlY coatings were generally more effective than the simple aluminide and the Pt, Rh-aluminide in providing protection to first stage vanes. A remnant coating thickness index (RCTT) was used to express coating survival and protectiveness quantitatively. The results of the study have been compared with literature.
