PRODUCTION METHOD OF METAL PART REINFORCED WITH CERAMIC FIBRES Russian patent published in 2013 - IPC C22C47/20 C22C47/04 

Abstract RU 2499076 C2

FIELD: metallurgy.

SUBSTANCE: at least one lodgment (10A) is made in metal housing (10) having upper surface (10B) by means of a machining process. Then, at least one insert (11) made from ceramic fibres in metal matrix is arranged in the above lodgment; the above insert is covered with a cover plate; vacuumising of intermediate space around the above insert is performed and the above space is sealed. After that, a system formed with a metal housing with a cover plate is processed by isostatic sealing in hot condition and machining is performed to obtain a part. With that, the cover plate includes element (12) overlapping insert (11) arranged in a groove and projecting in relation to the above upper surface, as well as metal plate (14) overlapping upper surface together with the above element (12).

EFFECT: production of parts of elongated shape with a metal matrix and reinforcing elements from composite material with required operational characteristics.
