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
The Handbook of Environmental Degradation of Materials, Third Edition, explains how to measure, analyze and control environmental degradation for a wide range of industrial materials, including metals, polymers, ceramics, concrete, wood and textiles exposed to environmental factors, such as weather, seawater, and fire. This updated edition divides the material into four new sections, Analysis and Testing, Types of Degradation, Protective Measures and Surface Engineering, then concluding with Case Studies. New chapters include topics on Hydrogen Permeation and Hydrogen Induced Cracking, Weathering of Plastics, the Environmental Degradation of Ceramics and Advanced Materials, Antimicrobial Layers, Coatings, and the Corrosion of Pipes in Drinking Water Systems. Expert contributors to this book provide a wealth of insider knowledge and engineering expertise that complements their explanations and advice. Case Studies from areas such as pipelines, tankers, packaging and chemical processing equipment ensure that the reader understands the practical measures that can be put in place to save money, lives and the environment. Introduces the reader to the effects of environmental degradation on a wide range of materials, including metals, plastics, concrete, wood and textiles Describes the kind of degradation that effects each material and how best to protect it Includes case studies that show how organizations, from small consulting firms, to corporate giants design and manufacture products that are more resistant to environmental effects

Book Description
The great advantages, in terms of economy and performance, to be gained by using high performance ceramics in applications such as the gas turbine engine have spurred development efforts in the non-oxide ceramic area and in hardware applications. However, relatively little effort has been devoted to examining in detail the factors which may limit lifetimes in the above applications in which long lifetimes have been traditionally demanded. The purpose of this research project was to use a fundamentally based fracture mechanics approach to examine the susceptibility of Si3N4 and SiC ceramics to stress-corrosion in water and various gaseous environments over a range of temperatures. Further, the fundamental mechanism(s) which contribute(s) to the observed slow crack growth were to be elucidated. In addition, an effort was initiated to investigate the mechanism(s) by which molten salt environments may limit strengths and lifetimes of these materials. (Author).
