Abstract

The invention provides a batch-type electrodeposition core-shell-type powder electroplating device and a treatment method thereof. The batch-type electrodeposition core-shell-type powder electroplating device comprises an electroplating tank, a motor, a motor transmission shaft, a cathode plate, a stirring structure, a clamping structure, an anode plate and a power supply; the motor is located at the bottom outside the electroplating tank; the motor transmission shaft is arranged on the motor and penetrates through the electroplating tank; the cathode plate is laid in the electroplating tank; the stirring structure is fixed to the motor transmission shaft through the clamping structure and arranged in the electroplating tank; the anode plate is fixed to the motor transmission shaft and moves up and down along the motor transmission shaft; and the anode plate is located on the upper portion of the electroplating tank, and the power supply is connected with the anode plate and the cathode plate. Core-shell powder obtained through the electroplating device has the characteristics of being controllable in coating thickness, uniform in coating composition, free of impurities and the like, and can be widely applied to the fields such as powder metallurgy, 3D printing and cold spraying which use powder on a large scale.
