Abstract

The invention discloses a preparation method and a preparation device of metal niobium nanopowder, belongs to the field of metal processing, and provides the preparation method and the preparation device of the metal niobium nanopowder in order to solve the problems that an existing preparation method of the metal niobium nanopowder is low in preparation yield, high in preparation cost and not beneficial to industrial production. Power supply output waveforms and power supply parameters can be controlled through information fed back by an oscilloscope, and the dynamic characteristic of power supply discharge is improved by combining the control of components and temperature of a processing medium solution, so that the purpose of accurately controlling the arc discharge intensity on the surface of a workpiece is achieved, the electric arc is controlled to discharge from the nanometer level to the micrometer level according to requirements, it is ensured that powder from the nanometer level to the micrometer level can be generated when a pure metal niobium plate is bombarded by the electric arc every time, the nanometer-level metal niobium powder can be attached to the surface of the pure metal niobium plate, and later recovery is facilitated.

Description

technical field [0001] The invention belongs to the field of metal processing, and in particular relates to a preparation method and a preparation device of metallic niobium nanopowder. Background technique [0002] Nano-metal powders have important applications in many fields, and the preparation methods of nano-metal powders have also developed rapidly, from gas-phase methods, liquid-phase methods, and solid-phase methods to laser methods, plasma methods, and metal spray combustion methods. These methods all have the problems of low output and high cost; the price of the produced powder products is high (the price of nano-metal powder is usually dozens of times that of ordinary metal powder), which seriously restricts the application and promotion of nano-metal powder. [0003] Due to the contraction of lanthanide, niobium has extra electrons, and the metal bond of niobium becomes stronger, so it has a higher melting point and boiling point and a larger atomic enthalpy, hi...
