ABSTRACT:
A method including the step of applying braze alloy in sheet-like form to a part made of a brazeable parent metal. Pressure is exerted to place the braze alloy in intimately contacting relation to the part. For a predetermined period of time, while the exerted pressure is maintained, heat is applied at a temperature value which is just below the melting point of the braze alloy. Diffusion bonding occurs and, in accordance with an optional practice of the invention, a catalyst may be introduced which at a temperature below the applied temperature liquifies and speeds up the diffusion process.
