粉末冶金
粉末冶金（Powder metallurgy），是一种以金属粉末为原料，经压制和烧结制成各种制品的加工方法。粉末冶金工艺包含三个主要步骤，首先，主要组成材料被分解成许许多多的细小颗粒组成的粉末；然后，将粉末装入模具型腔，施以一定的压力，形成具有所需零件形状和尺寸的压坯；最后，对压坯进行烧结。
粉末冶金零件生产工艺的本质性优势是，具有零件最终形成形能力和材料利用率很高。

Powder metallurgy 粉末冶金
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs
