Abstract
An interlayer for transient liquid phase diffusion bonding is provided by depositing a metallic coating on at least one of the superalloy surfaces to be bonded and boriding a portion of the metallic coating to form a working coating having an overall composition resembling that of an interlayer alloy and an overall melting temperature less than that of the superalloys. When the superalloy surfaces are placed in contact and heated to above said melting temperature, the partially borided metallic coating functions as an interlayer alloy to effect bonding.
