Available in PDF, EPUB and Kindle. Book excerpt: Turbine section hardware in marine engines is susceptible to hot corrosion attack induced by salt deposition. In attempting to control this type of materials degradation, it is necessary to examine the dependence of hot corrosion on ingested salt level and to determine the deposition rate below which hot corrosion attack will be negligible. Test specimens (uncoated and aluminized Mar-M509 and IN792, CoCrAlY-coated IN 792) were exposed at 700 and 900 C in laboratory tube furnaces to conditions which induce hot corrosion attack. The microstructures developed in these tests were compared with those observed in service hardware. A test at 700 C with a salt deposit of sodium sulfate, either pure or mixed with metallic sulfates, and a gaseous environment of oxygen with approximately .0001 atm SO3 was found to most closely duplicate the degradation microstructure most common in hardware from marine service. Results support the hypothesis that any condensed salt deposit is likely to produce unacceptable hot corrosion and hence the only safe ingestion level is that which produces no salt deposition on turbine hardware.

Available in PDF, EPUB and Kindle. Book excerpt: The new edition of LaQue's classic text on marine corrosion, providing fully updated control engineering practices and applications Extensively updated throughout, the second edition of La Que's Handbook of Marine Corrosion remains the standard single-source reference on the unique nature of seawater as a corrosive environment. Designed to help readers reduce operational and life cycle costs for materials in marine environments, this authoritative resource provides clear guidance on design, materials selection, and implementation of corrosion control engineering practices for materials in atmospheric, immersion, or wetted marine environments. Completely rewritten for the 21st century, this new edition reflects current environmental regulations, best practices, materials, and processes, with special emphasis placed on the engineering, behavior, and practical applications of materials. Divided into three parts, the book first explains the fundamentals of corrosion in marine environments, including atmospheric corrosion, erosion, microbiological corrosion, fatigue, environmental cracking, and cathodic delamination. The second part discusses corrosion control methods and materials selection that can mitigate or eliminate corrosion in different marine environments. The third section provides the reader with specific applications of corrosion engineering to structures, systems, or components that exist in marine environments. This much-needed new edition: Presents a comprehensive and up-to-date account of the science and engineering aspects of marine corrosion Focuses on engineering aspects, descriptive behavior, and practical applications of materials usage in marine environments Addresses the various materials used in marine environments, including metals, polymers, alloys, coatings, and composites Incorporates current regulations, standards, and recommended practices of numerous organizations such as ASTM International, the US Navy, the American Bureau of Shipping, the International Organization for Standardization, and the International Maritime Organization Written in a clear and understandable style, La Que's Handbook of Marine Corrosion, Second Edition is an indispensable resource for engineers and materials scientists in disciplines spanning the naval, maritime, commercial, shipping industries, particularly corrosion engineers, ship designers, naval architects, marine engineers, oceanographers, and other professionals involved with products that operate in marine environments.

Book excerpt: The phenomenon of hot corrosion in marine gas turbines is stimulated by the presence of sodium sulfate. Two avenues can be followed to minimize deterioration by hot corrosion: (1) control of environmental conditions to prevent the formation of a molten slag and (2) development of materials to resist corrosive attack. Several techniques have been proposed to curtail the formation of a fused slag: limiting the gas turbine operating temperature which, though effective, seriously limits efficiency and fuel economy (present method); eliminating sea salt from the combustion zone by filtering to avoid formation of the aggressive environment; and other promising techniques for controlling environmental conditions such as blade cooling and fuel additives. The development of materials with built-in hot corrosion resistance would provide the most desirable solution to the problem. Therefore, considerable effort is being expended to devise tailor-made coatings and alloys. Supporting the development efforts are mechanism studies which are aimed at understanding of the interactions between the marine gas turbine environment and hot section materials, and identifying beneficial alloying constituents. Experience so far indicates that none of the specific approaches alone will provide a complete solution to the problem. (Author).

Book excerpt: Discrepancies between early hot-corrosion models based on sulphidation and more recently reported data obtained by a molten salt fluxing technique are discussed. The hot corrosion role of sulphur in the absence of salt was tested by presulphidizing specimens at high and low sulphur partial pressures and then oxidizing them. Results show that certain features of the practical hot corrosion reaction are not well-modeled by the salt-fluxing model and that sulphur played a more important part than predicted. (Author).

This book was released on 1970 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot corrosion (sulfidation) in gas turbine engines has become a major problem because of the increased use of alloys low in chromium and the operation in environments containing alkali metal salts, especially near sea water. Sulfur can enter a gas turbine from the fuel, and chloride and sulfate salts from the air. There is little prospect for removal of these contaminants to such a degree as to eliminate the problem. However, from 10 to 75% of sea salt can be removed from the air intake to retard the attack. Data on tolerable levels of contaminants are needed. Engine testing is still the only reliable evaluation method to check improvements in the hot corrosion resistance of materials. Reproducibility in test results from test rigs in different laboratories is very poor, and further effort toward test rig standardization, correlation of the data between different tests, and interpolation of tests results and extension to different testing conditions, all are needed. Specific recommendations for attacking the hot corrosion problem are detailed in the report. (Author).
