Problems solved by technology

However, the molten liquid of the Fe-Co alloy is very viscous, and it is very easy to block the pipeline, resulting in the failure of the gas atomization method. In addition, there is no place to purchase Fe-Co alloy powder with the target ratio requirement on the market, so that Fe -The preparation and development of Co-based alloy sputtering targets have been greatly hindered

Abstract

The invention relates to an iron-cobalt-tantalum alloy powder preparation method, iron-cobalt-tantalum alloy powder, and an application. The iron-cobalt-tantalum alloy powder preparation method includes the steps that firstly, iron, cobalt, and tantalum are prepared according to a target atomic ratio and mixed; then the iron, the cobalt, and the tantalum are melted completely under the temperatureof 1650-1750 DEG C; and then atomizing is carried out under the action of inert gas, and the iron-cobalt-tantalum alloy powder is obtained. According to the preparation method, the melting temperature of an iron-cobalt-tantalum mixture is controlled at 1650-1750 DEG C, and the atomizing conditions are optimized, so that the purity of the prepared iron-cobalt-tantalum alloy powder is greater thanor equal to 99.95%, and the oxygen content is less than or equal to 600 ppm. The iron-cobalt-tantalum alloy powder with the particle size less than 150 meshes is obtained by sieving, which is conducive to the preparation of an iron-cobalt-tantalum alloy sputtering target material with high purity, high density, high bending strength and qualified magnetic flux. Tantalum scrap of a tantalum targetmaterial is used as a tantalum material for preparation, which realizes the transformation of waste into treasure.

Description
