Abstract
A diffusion bonding process for bonding one rhenium-coated carbonaceous body to another. The rhenium-coat surfaces 18,20 of the bodies are coated with ruthenium, and the bodies are diffusion bonded at the interface formed by adjoining ruthenium coats 22,24.
Claims17
A diffusion bonding process for bonding a first carbonaceous body to a second carbonaceous body at an interface formed between substantially conformal bonding surfaces formed on the bodies, comprising the steps of:
- depositing a first coating that comprises rhenium onto the bonding surfaces to form a rhenium-coat surface on each of the bodies;
- depositing a second coating that comprises ruthenium onto the rhenium-coat surfaces to form a ruthenium-coat surface on each of the bodies;
- orienting the bodies so that the ruthenium-coat surfaces are in adjoining relation, whereby the interface is formed;
- and
- pressing the bodies together at the interface and simultaneously heating the bodies until the bodies cohere at the interface.
