Abstract
The present disclosure provides methods for preparing magnetostrictive powder and magnetostrictive coating, and relates to the field of magnetic functional materials and preparation thereof. The method for preparing magnetostrictive powder includes putting metals for preparing magnetostrictive powder into a vacuum melting furnace to be melted into a solution; and atomizing the solution into fine droplets by ultrasonic atomization, so that the fine droplets are cooled and solidified into magnetostrictive powder. In the method for preparing magnetostrictive powder according to the embodiments of the present disclosure, the sizes of the prepared powder are relatively uniform, the powder yield exceeds 90%, the ultrasonic atomization energy consumption is low, and energy is saved by about ¼ compared with conventional atomization.
