一、序言: 随着喷气技术、原子核工程及宇宙飞行等三大尖端技术的迅速发展,近代粉末冶金借助于解决这些尖端技术所需要的材料而日益进步。其中,包复粉末也引起了人们极大的重视。现在能够将金属包复在另一金属粉末颗粒上,也可将陶瓷包复在金属粉末颗粒上,还可将金属包复在陶瓷粉末颗粒上,甚至还可将陶瓷包复在另一陶瓷粉末颗粒上。 I. Preamble: With the rapid development of the three cutting-edge technologies such as jet technology, atomic nuclear engineering and space flight, modern powder metallurgy is making progress with the materials needed to solve these cutting-edge technologies. Among them, the complex powder also caused great attention. It is now possible to coat the metal on another metal powder particle, to coat the ceramic on the metal powder particle, to clad the metal on the ceramic powder particle, to even coat the ceramic in another ceramic powder Particles.
