Preparation method of ceramic powder for plasma physical vapor deposition
The invention discloses a preparation method of ceramic powder for plasma physical vapor deposition, which comprises the following steps of in order to meet the porous requirement of a powder materialin a PS-PVD process, adding a pore-forming agent into ingredients, carrying out atomization granulation, and setting a burning step to remove the pore-forming agent in the powder material, and on thebasis of no influence on the strength of powder particles, realizing the requirement for the porosity of powder particles. Meanwhile, the mode that overflow classification and airflow classificationare combined is adopted, the granularity of the powder is accurately controlled, the technological requirement of PS-PVD is met, and finally the powder material which is small in particle size, porousin structure and good in fluidity is obtained. The preparation method has the advantages of being simple, easy to operate, suitable for application and popularization and the like.
本发明公开了一种等离子物理气相沉积用陶瓷粉末的制备方法，为了满足PS‑PVD工艺中粉末材料的多孔要求，在配料中加入了造孔剂，且雾化造粒后设置了排烧步骤，将粉料中的造孔剂去除，在粉料颗粒自身强度没有受到影响的基础上，实现了对于粉末颗粒的多孔要求，同时，该制备方法通过采用溢流分级与气流分级相结合的方式，实现对粉料粒度的精确控制，以满足PS‑PVD的工艺要求，最终获得粒径小、结构多孔、流动性良好粉末材料；该制备方法，具有简单、易操作，适于应用推广等优点。
