Experience in the Manufacture of Gas Turbine Vanes of Hot Pressed Silicon Nitride and Silicon Carbide

The introduction of ceramic vanes into gas turbines has required simultaneous materials and manufacturing development programs. A review of the materials development programs is presented to show that hot pressed silicon nitride and silicon carbide are consistent engineering materials. A discussion of general machining parameters including diamond wheel specifications is presented to provide guidance in the preparation of turbine components from hot pressed silicon nitride and silicon carbide.Copyright © 1975 by ASME
