POWDER METALLURGY SCISCIE

中文简介

粉末冶金是由三个主要加工阶段组成的成形和制造技术。首先，原材料是物理粉末，分为许多小的单个颗粒。接下来，粉末被注入模具或通过模具，以产生一个弱粘性结构（通过冷焊接），非常接近最终要制造的物体的尺寸。最后，端部通过施加压力、高温、长凝固时间（发生自焊）或其任何组合形成。

英文简介

Powder metallurgy is a forming and fabrication technique consisting of three major processing stages. First, the primary material is physically powdered, divided into many small individual particles. Next, the powder is injected into a mold or passed through a die to produce a weakly cohesive structure (via cold welding) very near the dimensions of the object ultimately to be manufactured. Finally, the end part is formed by applying pressure, high temperature, long setting times (during which self-welding occurs), or any combination thereof.
