ASSEMBLY OF METAL PARTS AND PARTS EXECUTED FROM CERAMIC MATERIAL BASED ON SiC AND / OR BASED ON

摘要

1. Assembling a metal part (1) with a ceramic part (7) made of a ceramic material based on silicon carbide (SiC) and / or carbon (C), characterized in that it contains a multilayer structure comprising elements connected together in pairs in the following the order by soldering the metal part (1), the first intermediate part (3), the second intermediate part (5) and the part (7) of ceramic material, while the second intermediate part (5) is made of another ceramic material chemically less reactive with respect to contact with metals than silicon carbide (SiC) or carbon (C) and having an expansion coefficient less than the expansion coefficient of the material of the metal part (1), and the first intermediate part (3) is made of metal and is able to deform to compensate for the difference in expansion between the metal part (1) and the second intermediate part (5). ! 2. The assembly according to claim 1, characterized in that the second intermediate part (5) has a hardness and / or tensile strength greater than the hardness and / or tensile strength of the ceramic part (7). ! 3. The assembly according to claim 1, characterized in that said part (7) of a ceramic material is made of solid silicon carbide (SiC). ! 4. The assembly according to claim 1, characterized in that the part (7) of a ceramic material is made of a ceramic matrix composite material. ! 5. The assembly according to claim 4, characterized in that the composite material includes a matrix based on silicon carbide (SiC) and / or carbon (C), reinforced with fibers of silicon carbide (SiC) and / or carbon (C). ! 6. The assembly according to claim 1, characterized in that said metal part (1) is made of alloy
