ABSTRACT:
A compositionally graded gas turbine disk is made by preparing a rotationally symmetric radially inner segment of a gas turbine disk preform, rotating the inner segment about a central axis, spray applying a radially outer-segment material onto the radially inner segment as it rotates about the central axis, preferably achieving a gradual transition in composition, and thereafter further processing the gas turbine disk preform to produce the compositionally graded gas turbine disk.
