METHOD FOR PRODUCING NICKEL-CHROMIUM ALLOY X20H80 SINTERED FROM ELECTROEROSIVE POWDERS OBTAINED IN KEROSENE Russian patent published in 2022 - IPC B22F3/14 C22C1/04

Abstract RU 2772880 C1

FIELD: powder metallurgy.

SUBSTANCE: invention relates to powder metallurgy, in particular, to the production of sintered nickel-chromium alloys. It can be used for the manufacture of general engineering products. The sintered alloy is produced by spark plasma fusion of the charge obtained by electroerosive dispersion of X20H80 alloy waste in lighting kerosene at temperature T=1240°C, pressure P=40 MPa and holding time t=10 min.

EFFECT: invention provides an increase in physical and mechanical properties.
