| 摘要 |
The present invention relates to a powder metallurgy method and, more specifically, to a powder metallurgy method including a process of producing a liquid lubricant through a high-temperature stirring process of mixing a lubricant component having a predetermined composition ratio of ethylene bis stearamide and erucamide at 150 to 170°C, then cooling and pulverizing the liquid lubricant to produce a solid lubricant, and adding the solid lubricant to metal-based powder. Accordingly, the content of the lubricant added to the metal-based powder is minimized, shaping energy and extraction energy are kept in an equivalent or improved level, and a high-density shaped body is produced. |
