Abstract RU 2664119 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to a method for the additive manufacture of a component of a composite with a metal matrix. Method includes an electron beam melting of a powder mixture which contains powdered tungsten carbide in an amount of 45 to 72 % by weight of the pulverulent mixture and a powdery binder in an amount of from 28 to 55 % by weight of the weight of the powder mixture. Said powdered binder contains nickel in an amount of at least 70 % by weight of the weight of the powdery binder.

EFFECT: increased resistance to wear, erosion, corrosion and impact.
