Abstract: The invention relates to a joint between a metal part (1) and a ceramic part (7) which is made from a ceramic material that is based on SiC and/or C. The inventive joint is characterised in that it comprises a stacked structure consisting of the following elements which are assembled in pairs, in the following order, by means of brazing, namely: the metal part (1), a first spacer (3), a second spacer (5), and the ceramic part (7). According to the invention, the second spacer (5) is made from another ceramic material which is less chemically reactive with metals than SiC or C and which has a lower expansion coefficient than that of the material forming the metal part (1). Moreover, the first spacer (3) is metal and can deform in order to compensate for the expansion differential between the metal part (1) and the second spacer (5). The invention also relates to the use of said joint in a turbomachine.

Abstract: The invention relates to a joint comprising a metal part, a ceramic part and at least one connecting spacer which is assembled to each of said parts by means of brazing. The aforementioned connecting spacer (10') consists of a deformable layer having at least two flat areas (11, 12) which are brazed respectively to the above-mentioned parts. Moreover, said two flat areas (11, 12) are interconnected by a deformable area (13') having at least two non-brazed undulations (19, 20) which are oriented alternately towards the metal part and the ceramic part.
