LOW BINDER SINTERED CARBIDES AND ITS MANUFACTURING METHOD |
摘要 |
PURPOSE: A sintered carbide and a manufacturing method thereof are provided to have high hardness, high toughness, and high strength and to prevent grain growth. CONSTITUTION: A manufacturing method of a sintered carbide is as follows: a step of mixing and crushing material powder at the same time to manufacture raw material powder (S100); a step of separating a sintered ball and slurry and drying the separated slurry with a spray dryer to manufacture press powder (S200); a step of forming the press powder with hydraulic press to manufacture a formed body (S300); a step of sintering the formed body in a vacuum furnace at 1400°C-1600°C to manufacture a sintered product (S400); and a step of hot isostatic pressing the sintered product (S500). [Reference numerals] (S100) Step of manufacturing raw material powder; (S200) Step of manufacturing press powder; (S300) Step of manufacturing a formed body; (S400) Step of sintering the formed body to manufacture a sintered product; (S500) Step of hot isostatic pressing the sintered product |
