Low binder, wear resistant hard metal |
摘要 |
The invention is a low binder, wear resistant material including, in weight percent of raw materials, from 15% to 20% of molybdenum carbide added in either elemental or compound form, an alloy of 0.9% to 3% cobalt, nickel or a combination of cobalt and nickel, of 0 to 0.1% of chromium carbide, optionally also titanium carbide or titanium tungsten carbide and the balance of tungsten carbide. |

1. A method of making a low binder, wear resistant material comprising the steps of
providing from about 15 to of about 20% of molybdenum carbide added in either individual molybdenum and carbon elemental or compound form, providing about 0.9 to of about 3% of cobalt, nickel or a combination of cobalt and nickel, providing 0 to of about 0.1% of chromium carbide, and providing the balance of tungsten carbide to form a powder blend; milling the powder blend; drying the powder blend; sieving the powder blend; pressing the powder blend; and sintering the powder blend at a temperature of from about 1450° C. under a pressure of about 50 bar in an argon atmosphere. |
