Method for preparing powder material and application thereof

Abstract

The present disclosure provides a method for preparing a powder material and an application thereof. The preparation method includes: obtaining an initial alloy ribbon including a matrix phase and a dispersed particle phase by solidifying an alloy melt, and then removing the matrix phase in the initial alloy ribbon while retaining the dispersed particle phase, so as to obtain a powder material composed of original dispersed particle phase. The preparation method of the present disclosure is simple in process and can prepare multiple powder materials of nano-level, sub-micron-level and micro-level. The powder materials have good application prospects in the fields such as catalytic materials, powder metallurgy, composite materials, wave-absorbing materials, sterilization materials, metal injection molding, 3D printing and coating.
