This book addresses the problem of surface protection for aircraft engine turbine blades. It is based on the authorAs 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.
Contents include: Choosing Proper Coatings for Modern Aircraft Engine Turbine Blades Production Processes for Electron Beam and Electric Arc Evaporation Coatings Phase Composition of Coatings on Superalloys Phase and Structural Changes in Coatings During High-Temperature Tests Turbine Blade Coating Protective Properties Effect of Protective Coatings on the Mechanical Properties of Turbine Blade Superalloys Thermal Barrier Coatings Strength Designing of Turbine Blade Protective Coatings.
