Patent ID: 8757475

Claim:
A method of assembling at least one part made of a porous carbon-based material with at least one part made of a copper-rich metallic material, comprising the following steps: a) deposition of an alloy based on copper and silicon having the following formula: Cu x Si y in which x and y are atomic percentages where x is 60 and y is 40, or on the assembly surface of the at least one part made of a porous carbon-based material, so as to have an amount of brazing alloy of between 50 and 500 mg/cm 2 ; b) heating of the whole assembly obtained in step a), in a vacuum or in an inert atmosphere, so as to melt said alloy or said paste; c) contacting of the whole assembly obtained in step b) with the assembly surface of said at least one part made of a copper-rich metallic material; and d) heating of the whole assembly obtained in step c) at a temperature below the melting point of said at least one part made of a copper-rich metallic material and below the melting point of said alloy or of said paste, in a vacuum or in an inert atmosphere.
