DEVELOPMENT OF A CERAMIC BLADE-SUPERALLOY DISK ATTACHMENT FOR GAS TURBINE ROTORS

With improving ceramic materials and fabrication techniques, a major effort is underway to design and test ceramic hot flow path components for gas turbine engines. The most critical and furthest from a satisfactory engineering solution is the turbine rotor. This paper summarizes the development of a new technique for attaching hot pressed silicon nitride ceramic airfoil shapes to a wrought AF2-1DA superalloy disk using the GATORIZING isothermal forging rocess. /GMRL/
