Book Description
Baseline and simulated environment post-exposure test results of fourteen candidate ceramic materials for stationary power-generating gas turbines are presented. The materials studied were various material types of silicon nitride, silicon carbide, aluminum nitride, A1203-Zr02, A1203-SiC, MgA1204 spinel, and SiA1ON. One dynamic (1425 deg C, 305 m/s, 1000 hr) and nine static (1000 deg, 1200 deg, and 1425 deg C for 100, 300, and 1000 hr) exposures were conducted at the Morgantown Energy Technology Center facility of the Department of Energy. The exposure environment was coal-derived fuel gas combustion products created in a fixed-bed gasification system. Post-exposure evaluation involved evaluation of surface chemistry and morphology, weight and dimension change, retained room-temperature strength and fracture surface analysis. Based upon limited testing and the small sample population available, the materials are ranked according to their probable survivability in power turbine applications.

Book Description
Ceramic materials, silicon nitride and silicon carbide in particular, are under intensive engineering development for gas turbine applications. One of the factors which has encouraged this line of development is the excellent corrosion/erosion behavior of these ceramics. This paper will briefly review some of the fundamental mechanisms and critical materials properties thought to govern the corrosion/erosion behavior of ceramics and point out where these differ from those of metals. A review of available erosion, corrosion, and combined corrosion/erosion testing of silicon nitrides and silicon carbides will be presented. While the results of these tests are quite encouraging it is evident that there is a lack of data at high temperatures, in atmospheres containing multiple contaminates, and there is virtually no long-duration testing information. The author will suggest areas of research required to further our understanding of corrosion/erosion behavior and phenomena, and provide a more extensive data base for future engineering applications.

Book Description
Corrosion of Ceramic and Composite Materials, Second Edition is a primary source of guidance for the assessment, interpretation, and inhibition of corrosion phenomena. This book discusses all aspects of corrosion of ceramics, including environments, mechanisms, and materials, and the means to minimize or eliminate corrosion. The author compiles key findings and literature highlights from nearly a decade of scientific advancement, covering emerging techniques in corrosion analysis, characterization, and prediction. He provides at-a-glance coverage of national and international testing procedures for the evaluation of materials stability. The book covers the fundamentals of corrosion by gases, liquids, and solids of several ceramic materials including crystalline materials, glasses, composites, bioceramics, and advanced ceramics. It also discusses property/corrosion relationships and testing. The book collects a generous number of models, figures, and studies illustrating techniques to minimize and reduce the effects of various mechanisms contributing to the corrosion of civil, aerospace, and military structures. The second edition includes a review of all the current literature since publication of the first edition, an additional chapter on composites, and major sections added on bioceramics and weathering of construction materials. Corrosion of Ceramic and Composite Materials, Second Edition explains existing corrosion problems and offers an excellent guide to the design and development of corrosion-resistant structures.
