Protective Coatings for Turbine Blades by Y. Tamarin Pdf

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.

Advances in wind turbine blade design and materials by B. Kjærside Storm Pdf

This chapter discusses surface layer protection for wind turbine rotor blades. The surface protection and coating can be a gelcoat or a paint and can be made of unsaturated polyester, epoxy, polyurethane or acrylic. As wind turbines are often erected in harsh climates, the blade surface will be exposed to conditions that cause erosion and wear. There are tests to measure resistance against these attacks, and the surface is designed to minimize damage to the blade caused by the environment. By using existing standards for surface layers for offshore use and for helicopters, it has been found that a combination of accelerated tests for UV degradation, chemical attack and wear give a complete picture of the performance of surface layers.

Environmental Barrier Coatings by Kang N. Lee Pdf

The global increase in air travel will require commercial vehicles to be more efficient than ever before. Advanced engine hot section materials are a key technology required to keep fuel consumption and emission to a minimum in next-generation gas turbines. Ceramic matrix composites (CMCs) are the most promising material to revolutionize gas turbine hot section materials technology because of their excellent high‐temperature properties. Rapid surface recession due to volatilization by water vapor is the Achilles heel of CMCs. Environmental barrier coatings (EBCs) is an enabling technology for CMCs, since it protects CMCs from water vapor. The first CMC component entered into service in 2016 in a commercial engine, and more CMC components are scheduled to follow within the next few years. One of the most difficult challenges to CMC components is EBC durability, because failure of EBC leads to a rapid reduction in CMC component life. Key contributors to EBC failure include recession, oxidation, degradation by calcium‐aluminum‐magnesium silicates (CMAS) deposits, thermal and thermo‐mechanical strains, particle erosion, and foreign object damage (FOD). Novel EBC chemistries, creative EBC designs, and robust processes are required to meet EBC durability challenges. Engine-relevant testing, characterization, and lifing methods need to be developed to improve EBC reliability. The aim of this Special Issue is to present recent advances in EBC technology to address these issues. In particular, topics of interest include but are not limited to the following: • Novel EBC chemistries and designs; • Processing including plasma spray, suspension plasma spray, solution precursor plasma spray, slurry process, PS-PVD, EB-PVD, and CVD; • Testing, characterization, and modeling; • Lifing.

Protective Coatings and Thin Films by Y. Pauleau,Péter B. Barna Pdf

This volume entitled "Protective Coatings and Thin Films : Synthesis, Characterization and Applications" contains the Proceedings of the NATO Advanced Research Workshop (ARW) held in Alvor, Portugal from May 30 to June 5, 1996. This NATO-ARW was an expert meeting on the surface protection and modification of solid materials subjected to interactions with the environment. The meeting attracted 10 key speakers, 40 contributing speakers and 3 observers from various countries. The existing knowledge and current status of the science and technology related to protective coatings and thin films were assessed through a series of oral presentations, key notes (titles underlined in the volume content) and contributed papers distributed over various sessions dealing with: (a) plasma-assisted physical and chemical vapor deposition processes to enhance wear and corrosion protection of materials, (b) low friction coatings operating in hostile environment (vacuum, space, extreme temperatures, . . . ), (c) polymer films for protection against mechanical damage and chemical attack, (d) characterization of the structure of films and correlations with mechanical properties, (e) wear and corrosion resistant thermal spray coatings, (f) functional gradient ceramic/metallic coatings produced by high energy laser beam and energetic deposition processes for high temperature applications, (g) protective coatings for optical systems, and (h) ion beam assisted deposition of coatings for protection of materials against aqueous corrosion.

Advanced Methods and Technologies in Metallurgy in Russia by Stavros Syngellakis,Jerome J Connor Pdf

The book provides a comprehensive overview of the most recent and advanced work on metallurgy sciences and technologies--including material characterization of complicated alloys, heat and surface treatment, ferrous metals metallurgy, and energy savings in pyrometallurgy--in the important Ural industrial region of Russia. Until recently, research into scientific and engineering problems within Russia developed along different lines than those in Europe and North America, but nevertheless resulted in remarkable achievements utilizing different tools and methodologies than those used in the West. Many of these achievements – particularly in metallurgy – were made in the Urals.

High Temperature Protective Coatings for Aero Engine Gas Turbine Components by J-P. A. Immarigeon,P. C. Patnaik,National Research Council Canada,National Aeronautical Establishment (Canada) Pdf

Aluminide coatings have been widely used in the aircraft industries for the protection of gas turbine engine hot section components against oxidation and/or hot corrosion. This paper considers modes of coating degradation under conditions of cyclic oxidation, hot corrosion and corrosion-erosion interactions during service as well as the effects of interdiffusion between coating and substrate alloys either during service or coating application. It also discusses means of improving existing coatings as well as advanced coating systems currently under development. In assessing coating performance, consideration must be given to the influence coatings may have on substrate properties such as mechanical strength, resistance to creep and resistance to mechanical and thermal fatigue. Finally it is stressed that proven performance for a given coating/substrate combination is no guarantee that no deleterious reaction will occur, when the same coating is used with a different substrate alloy. Therefore, coating substitution requires requalification. Keywords: Aircraft engines; Protective coatings.
