METHOD FOR PRODUCTION OF POWDER FROM LUMP WASTE OF HARD ALLOYS

摘要

The invention relates to the powder metallurgy, namely - to the method of obtaining the powder from the lump waste of hard alloys. A method for obtaining powder from the lump waste of hard alloys includes its crushing to the granules by electro-erosion dispersion in the aqueous medium with at pH 7-8 and additional treatment by inorganic acids and/or by electrochemical treatment. The invention ensures the improvement of quality of obtained powder of hard alloys for their subsequent use according to the direct purpose.
