ASSEMBLY OF METAL PART AND PART MADE OF CERAMIC MATERIAL ON BASE OF SiC OR ON BASE OF C Russian patent published in 2011 - IPC C04B37/02 

FIELD: machine building.

SUBSTANCE: assembly of metal part (1) made of alloy on base of nickel or cobalt and part (7) made of ceramic material on base of silicon carbide (SiC) and/or carbon (C) has multi-layer structure including following elements connected by soldering in pairs in following order: metal part (1), first intermediate part (3), second intermediate part (5) and part of ceramic material. Second intermediate part (5) is made of aluminium nitride and/or mullite with expansion coefficient less, than expansion coefficient of material of metal part (1). First intermediate part (3) is fabricated of malleable metal and is capable to deform for compensation of difference of expansion between said metal part (1) and second intermediate part (5).

EFFECT: assembly compensates difference in expansion between metal and ceramic part and prevents formation of undesirable chemical compounds and local deformations.
