FIELD: powder metallurgy.
SUBSTANCE: invention can be used in the manufacture of powder compositions for running-in sealing coatings of turbomachine parts obtained by chemical metallization, for example, chemical nickel plating. The nickel-based powder composition contains hexagonal boron nitride, while it additionally contains phosphorus and impurities in the following ratio, wt.%: nickel - base, hexagonal boron nitride - 17.0-23.0, phosphorus - 1.0-10.0, impurities - no more than 2.0.
EFFECT: obtaining a coating from a powder composition with high erosion resistance, acceptable hardness for running-in sealing coatings of turbomachines.
