FIELD: construction.
SUBSTANCE: this compound may be used in aviation, in particular, in turbomachine, to connect parts included into the composition of a nozzle, a combustion chamber and an afterburner. The joint comprises a multi-layer structure, which includes the following components joined to each other by means of soldering: a titanium-based metal part (10), the first substrate (11), capable of deformation for adjustment to the difference in expansion of the metal part (10) and a part of ceramic material (20) based on silicon carbide and/or carbon, the second rigid substrate (12) of aluminium (AIN) or tungsten (W) nitride with an expansion ratio that is close to the expansion ratio of the specified part from the ceramic material (20), and the part of the ceramic material (20).
EFFECT: creation of a soldered joint, which makes it possible to compensate for differences in expansion of the metal and ceramic part and to eliminate development of undesirable chemical compounds.
