PRESSING METHOD OF ELECTROTECHNICAL ITEMS FROM POWDER COMPOSITIONS BASED ON CARBON |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: preliminary hot pressing of powder composition at die speed 10÷12 mm/s with specific pressure 20÷30 MPa, and further holding at this pressure for 0.5÷1.5 minutes, and then hot pressing with specific pressure 50÷100 MPa is performed at pressing die speed 15÷30 mm/s.EFFECT: increased density of produced items by increasing of volume of removed gases and liquid vapours from back filled powder composition in matrix of press mould.1 ex |
