粉末冶金（P／M）为设计人员和用户提供了一种多用性、高效的零部件生产方法。称其具有多用性，是因为它可适用于简单形状和复杂形状的零部件制作，而且可使制作的零部件具有各种化学、物理及机械性能；称其高效，是因为它可生产从中等批量到大批量最终形状或近似最终形状的零 Powder metallurgy (P / M) provides designers and users with a versatile and efficient method of manufacturing components. Call it a versatile, because it can be applied to simple shapes and complex shapes of parts and components, and allows the production of parts with a variety of chemical, physical and mechanical properties; said its efficient, because it can produce from the medium Batch to high volume final shape or approximate final shape zero
