FIELD: technological processes. ^ SUBSTANCE: invention may be used to apply sealing run-in coating onto parts of gas-turbine engines in order to increase their efficiency factor, in particular by method of flame spraying. Cord material consists of shell made of organic material and core, which contains the following components, wt %: granulated technological filler 88-92, organic binder 8-12. Granulated technological filler contains the following components, wt %: graphite 2.5-4.5, hexagonal boron nitride 10.0-16.0, cadmium oxide 2.0-4.0, copper oxide 11.0-14.0, nickel - the rest. ^ EFFECT: increased resistance to erosion wear of coating in process of gas-turbine engine parts operation, by means of provision of its cohesion and adhesion strength of at least 3,0 MPa, reduction of coating porosity with simultaneous provision of ability for wearability and resistance to oxidation at the temperature of 700C in process of gas-turbine engine parts, for instance bodies of compressors. ^ 1 ex |
