Abstract

The invention discloses an ultrasonic electrical arc pulverizing device and belongs to the field of metal and alloy powder preparation devices including the ultrasonic electrical arc pulverizing device. The ultrasonic electrical arc pulverizing device comprises a cyclone separator. A glove box is mounted at an outlet of the cyclone separator. An outlet of a gas supercharging box is mounted at thetop of the glove box. A gas conveying pipeline is mounted on the gas supercharging box and connected with the tail of a standing wave device. An electric arc anode and an electric arc cathode are further mounted on the standing wave device. Wire feeders are mounted on the electric arc anode and the electric arc cathode correspondingly and electrically connected with an electrical arc spraying controller. An outlet of the standing wave device is located in an inlet of the cyclone separator. In view of the technical scheme, the powder preparation device provided by the invention can be high in efficiency, small in grain size and uniform in grain distribution.

Description

technical field [0001] The application belongs to the field of preparing metal and alloy powders, in particular, it relates to an ultrasonic arc powder making device and method. Background technique [0002] The existing mainstream methods for preparing metal powders include plasma rotary atomization, rotary crucible atomization, and high-pressure water atomization. [0003] The formation process of metal powder in the plasma rotary atomization method gas atomization, the expanding gas surrounds the molten liquid flow, causing disturbance on the surface of the molten metal, forming a cone. At the top of the cone, the expanding gas causes the molten metal to form a thin, thin sheet of liquid. Thin liquid sheets are unstable due to the high specific surface area. If the superheating of the liquid is sufficient, it can prevent the thin liquid sheet from solidifying prematurely, and can continue to withstand the shear force to form strips and eventually spherical particles. ...
