FIELD: metallurgy.
SUBSTANCE: according to the method, in metal housing (10) with upper surface (10B) there is at least one mounting seat (10A) for an insert. The mounting seat is provided with at least one insert (112) formed with ceramic fibres; the insert is closed with cover (12); intermediate space around the insert is vacuumised and tightly closed; metal housing with the cover is subject to isostatic sealing at high temperature and the above complex is treated to obtain the above part. Besides, insert (11) is straight-line, and the mounting seat for the insert in the metal housing forms straight-line groove (10A). The cover is made so that it can be arranged in the mounting seat on insert (11) with a gap after shrinkage as a result of cooling and can perform tight fit at expansion in the groove so that the above space can be closed.
EFFECT: simplifying the proposed technology at maintaining strength properties of the produced part.
