High-fluidity oxide eutectic high-entropy ceramic powder and preparation method thereof
The invention discloses high-fluidity oxide eutectic high-entropy ceramic powder and a preparation method thereof, and belongs to the field of ceramic materials. The preparation method comprises the following steps: (1) preparing single-phase high-entropy rare earth aluminate ceramic powder of multi-principal element solid solution; (2) preparing an oxide eutectic high-entropy ceramic sample piece; and (3) preparing the oxide eutectic high-entropy ceramic powder. By successfully preparing the oxide eutectic high-entropy ceramic powder and utilizing the excellent fluidity of the prepared oxide eutectic high-entropy ceramic powder, when the oxide eutectic high-entropy ceramic powder is used as a raw material of a laser additive manufacturing technology, the oxide eutectic high-entropy ceramic powder does not agglomerate and keeps relatively high fluidity, so that the uniformity and stability of a material sprayed by a laser nozzle are ensured; and smooth proceeding of laser additive manufacturing processing is ensured.
本发明公开了一种高流动性氧化物共晶高熵陶瓷粉末及其制备方法，属于陶瓷材料领域。本发明包括：(1)制备多主元固溶的单相高熵稀土铝酸盐陶瓷粉末；(2)制备氧化物共晶高熵陶瓷样件；(3)制备氧化物共晶高熵陶瓷粉末。本发明通过成功制备氧化物共晶高熵陶瓷粉末，利用制备得到的氧化物共晶高熵陶瓷粉末优异的流动性，使其作为激光增材制造技术的原材料时，不发生团聚而保持较高流动性，从而保证激光喷头喷出材料的均匀性及稳定性，保证激光增材制造加工顺利进行。
