METHOD FOR HARDENING ADDITIVE PRODUCTS FROM ELECTROEROSIVE COBALT-CHROMIUM POWDERS Russian patent published in 2021 - IPC B22F3/24 B22F3/105 B22F3/87

Abstract RU 2762689 C1

FIELD: powder metallurgy.

SUBSTANCE: invention relates to powder metallurgy, in particular to a method for hardening additive products from cobalt-chromium powders. It can be used for the manufacture of products for general engineering purposes. Additive products obtained by electrodispersing a cobalt-chromium alloy of the "Cellite" brand and sintering the resulting material on a 3D printer at a build rate of about 20 cm³/hour and a layer thickness of 50 mcm are hardened at an impact energy of 200 J and an impact frequency of 15 Hz.

EFFECT: improvement of physical, mechanical and operational properties of additive parts is provided.
