FIELD: powder metallurgy.
SUBSTANCE: invention can be used in the manufacture of powder compositions for sealing coatings of turbomachine parts obtained by chemical metallization, such as chemical nickel plating. Nickel-based powder composition obtained by chemical metallization, containing graphite, additionally contains phosphorus in the following ratio of components, wt.%: nickel - base, graphite - 17.0-28.0, phosphorus - 1.0-8.0, impurities - no more than 2.0.
EFFECT: obtaining a coating from a powder composition with the required hardness and high erosion resistance, increasing the performance of the coating at elevated temperatures.
