METHOD OF PRODUCTION OF POWDER MATERIAL BASED ON IRON WITH SILICON CARBIDE Russian patent published in 1997 - IPC

FIELD: powder metallurgy in particular, production of powder materials strengthened by crystals of silicon carbide. SUBSTANCE: after mixing of metal powders and silicon carbide the mix is poured in a mould and compacted at a pressure of 15 to 35 MPa, further moulding and caking are performed simultaneously passing through the mix alternating current of commercial frequency at a density of 10 to 35 A/sq.mm, pressure of 5-15 MPa for 3-25 s. EFFECT: facilitated procedure. 1 tbl
