BRAZED JOINT BETWEEN A TITANIUM-BASED METAL PART AND A CERAMIC PART BASED ON SILICON CARBIDE (SIC) AND/OR CARBON

摘要

Brazed joining between a titanium-based metal part and a silicon carbide (SiC) ceramic material part and / or carbon. This assembly comprises a stacked structure comprising the elements following two by two soldering: the metal part (10) based on titanium, a first interlayer (11) adapted to deform to accommodate a differential expansion between the metal piece (10) and a piece of ceramic material (20) based on silicon carbide and / or carbon, a second interlayer (12) rigid, with coefficient of expansion close to that of said ceramic material part (20) made of aluminum nitride (AIN) or tungsten (W), and the piece of ceramic material (20).
