粉末冶金包括制取金属粉末、制造金属零件和生产金属材料。它所制取的金属粉末,不仅是粉末冶金工业的主要原料,而且是许多民用以及国防与尖端科学部门的重要材料。由于粉末冶金是把金属粉末(或掺入部分非金属粉末)经过混合、成型和烧结,直接制成金属零件和材料,因此,它即是一项制造金属零件的少无切削新工艺;又是一项生产特殊材料和制品的新技术。
Powder metallurgy includes the preparation of metal powders, the manufacture of metal parts and the production of metal materials. The metal powder it makes is not only the main raw material for the powder metallurgy industry but also an important material for many civil and defense and cutting-edge science departments. Since powder metallurgy is a process of mixing, forming and sintering metal powders (or parts of nonmetallic powders) directly into metal parts and materials, it is a less non-cutting new process for manufacturing metal parts; and A new technology for producing special materials and products.
