Introduction and Status of the Ceramic Technology for Advanced Heat Engines Project

摘要

The Ceramic Technology for Advanced Heat Engines Project of the Advanced Materials Development Program was initiated in 1983 to meet the ceramic materials technology requirements of the companion DOE engine programs, the Advanced Gas Turbine Program, and the Heavy Duty Transport (low heat rejection heavy duty diesel) Program. Our goal is the technology base that will allow private industry to supply reliable and cost effective ceramics for applications in these advanced engines. Accordingly, our program includes the following objectives: improved and new synthesis and fabrication technology to improve the reliability of monolithic ceramics, toughened ceramic composites, and ceramic coatings; improved and new joining technology required for reliable ceramic attachments; an understanding of the physical and chemical mechanisms that control the friction and wear of ceramic materials and coatings under heat engine operating conditions; and identification and understanding of the mechanisms that control the long-term mechanical reliability of structural ceramics in advanced engine environments.
