FIELD: process engineering.
SUBSTANCE: invention relates to the parts of composite with ceramic matrix and can be used in aircraft engines, particularly, gas turbines or turbo machines of said engines. Surfacing of composite part consisting of fibres compacted by ceramic matrix with wavy and rough surface includes forming of ceramic coat on part surface. Liquid composition (20) containing polymer, a ceramics precursor, and hard refractory filler for cross-linking (40) of polymer and converting cross-linked polymer (50) into ceramic by heat treatment. After heat treatment, ceramic coating is impregnated with liquid metal composition that features thermal compatibility with part material. The part of composite C/SiC furnished with ceramic coating can be impregnated with composition of silicon-germanium or silicon-nickel.
EFFECT: high aerodynamic properties of the surface.
