Some Aspects of Materials and Structures Engineering with Ceramics for Engine Applications

摘要

This paper identifies the benefits of the use of ceramics in heat engines, how one designs with brittle materials, and some key materials for heat engine application. Current engineering and materials problems in the use of ceramics for engine applications are summarized. Examples of how the materials science and engineering community is addressing two of these problems: time and environmental dependence of properties, and development of improved high temperature (ca 1400 C) materials, are presented. A case history of a successful design of a ceramic engine component is also presented. Finally, progress on a variety of ceramic engine programs is reviewed. (Author)
