METHOD OF PRODUCTION OF CERMET POWDER OR CEMENTED CARBIDE Russian patent published in 2019 - IPC B22F9/04 B22F1/00 C22C29/00 B33Y70/00 B22F3/15 

Abstract RU 2687332 C2

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of powder from dense and spherically formed cermet granules. Method includes formation of spherically formed granules containing metal, solid components and organic binder, mixing said granules with sintering inhibitor powder, loading mixture into furnace chamber, heat treatment of mixture at sintering temperature with removal of organic binder from spherically formed granules, sintering solid constituent parts with metal in each spherically formed granule and forming a mixture of sintered dense spherically formed granules and powder of sintering inhibitor, unloading the mixture from the furnace chamber and separating the sinter inhibitor powder from the sintered dense spherically formed cermet granules, wherein the sintering inhibitor powder contains carbon.

EFFECT: higher quality of components produced by additive production from powder.
