NGK Insulators, Ltd. (NGK) fabricates ceramic turbine rotors and nozzle components for the Automotive Ceramic Gas Turbine development program (CGT program), conducted by the Petroleum Energy Center (PEC) of Japan. Both the rotor and nozzle components are made of silicon nitride. The turbine rotor is a radial type having a 127 mm tip diameter, and the segment type nozzle is formed integrally with either three or four vanes and shrouds. This paper discusses various processes of fabricating the ceramic components, dependence of the fabrication processes on dimensional accuracy, and the performance of each of the processes.
