    The invention relates to powder metallurgy, in particular powdered materials for thermal spraying of coatings resistant to corrosion and erosion.
    The purpose of the invention is to increase the erosion resistance of coatings.
    The proposed powder material consists of a mixture of a powder of a self-fluxing nickel-based matrix alloy containing, in wt.%: Chromium 18.0-35.0
    Iron0,1-25,0
    Bor0,5-4,5
    Silicon0.5-5.5
    Carbon 0.1-2.0
    and 20-80 wt.% powder of tungsten monocarbide. The matrix alloy may additionally contain 15 wt.% Molybdenum and / or 2 wt.% Niobium.
    Mainly the mixture consists of 50 wt.% Tungsten monocarbide and 50 wt.% Matrix nickel-based alloy containing, by weight,%:
