Download or read book Development of Protective Coatings for Columbium Alloy Gas Turbine Blades written by Seymour Priceman and published by . This book was released on 1972 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four developmental cycles of candidate selection, screening test and evaluation were performed on coatings for columbium turbine blade airfoils and root sections. Candidate coatings included numerous fused silicide compositions, silicided sintered underlays, and fused silicides plus glass, ceramic, soft metal, and flame sprayed overlays. The first three developmental cycles employed thermogravimetric analysis, isothermal furnace tests, slow cyclic tests, thermal fatigue torch tests, ballistic impact plus furnace oxidation tests, and prestrain plus oxidation tests as screening criteria. Extensive coating and coating processing compatibility studies were carried out with the aim of preventing deleterious reactions between root and airfoil coatings and degradation of the substrate alloy mechanical properties. The program was concluded with a series of advanced simulated environmental tests and mechanical property evaluations.

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.

This book was released on 1961 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed study was made of the formation and protective nature of surface alloy diffusion coatings for columbium. Vacuum vapor deposited, diffusion alloy coatings combining chromium, titanium and silicon were found to protect D-31 alloy f-48 alloy an unalloyed colu bium from surface oxidation or internal contamination for considerable lengths of time in air in the range of 2000 to 2600 F and for shorter periods up to 2800 F. Tests on the coating-base metal systems included cyclic oxidation, thermal shock and high velocity-hot gas erosion in a plasma flame.

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparative evaluation was made of 18 coatingbase metal systems, six different coatings applied to 3 Nb base materials (D-31 alloy, F-48 alloy and unalloyed Nb). The 18 coating-base metal systems were tested under the same conditions in cyclic oxidation (2300 and 2500 F), thermal shock (2 00 to 250 F), bend-oxidation (2500 F) nd stress-oxidation (2500 F) plus tensile tests. The tests produced directly comparable data between the coating-base metal systems relating to the protective nature of each coating and the effect of the coating and the coating treatment on the mechanical properties of the substrate.
