Abstract
Braze filler alloy is specifically applied and metallurgically bonded to a desired region of a nickel based superalloy workpiece using an electrospark deposition technique. The braze filler alloy is deposited onto, and concurrently metallurgically alloyed into, the desired region of the base metal by transfer of the material from the electrode using a short duration electrical impulse. The time and energy involved are small enough that total heat input to the base metal is minimal so that distortion and metallurgical structure changes of the base metal are negligible.
