METHOD OF PRECIPITATING DESIRED COMPOSITION OF SUPERALLOY Russian patent published in 2020 - IPC B23K9/04 B23K35/40 B23K35/30 

FIELD: metallurgy.

SUBSTANCE: invention can be used for deposition of superalloy during repair, restoration or production of components, for example, for gas turbine engine. Performing melting of core with coating, which is made as follows. First, elongated core element (20) is drawn, comprising a nickel-based or cobalt-based nickel-based alloy and at least one reinforcing component in reduced concentration, which provides the plasticity required for drawing. Coating (22) is applied on elongated element of core, containing at least one of said strengthening component, concentration of which is sufficient for obtaining deposited composition of superalloy of required composition at joint melting of elongated element of core and coating.

EFFECT: coating provides introduction of sufficient concentration of reinforcing component for recovery of high strength and low plasticity of superalloy.
