Device and method for synchronously producing different kinds of coated powders by electro-deposition

Abstract

The invention provides a device and method for synchronously producing different kinds of coated powders by electro-deposition. The device comprises an electroplating tank, a cathode plate, an anode assembly, a power component and a power supply. The cathode plate is laid at the bottom of the electroplating tank, and the anode assembly is placed above the electroplating tank through the connectionof the power component; and the power supply is connected with the anode assembly and the cathode plate through wires. The device breaks the disadvantage that a traditional device can only produce the same coated powder at a time. The device can be used in experimental teaching to explore the influence of electro-deposition parameters, electroplating liquid parameters and parameters of to-be-coated metal powder on the coated powders, and can also be used in the field of industrial large batch of powder using. In particular, the modification technology of the powder surfaces, that is, the coated powder prepared by the device has a great improvement on the fluidity and sinterability of original powders, and application prospects in the field of 3D printing, cold spraying and powder metallurgy are great.

Description

Technical field [0001] The invention belongs to the field of metal powder preparation, and relates to a device and method for producing coated powder by using an electrodeposition method, in particular to a device and method for simultaneously producing different types of coated powder by an electrodeposition method. Background technique [0002] Electrochemical deposition of metals from their compound solutions is the basis of hydrometallurgical and electrometallurgical processes. Generally speaking, the application areas of electrodeposition include electrolytic metallurgy, electrolytic refining, electroplating and electroforming. In the field of composite powder preparation, compared to the co-precipitation method, metal salt co-reduction method and displacement method, the electrodeposition method has become a promising method due to its simple process, low cost, simple composition of the plating solution and no impurities. method. [0003] Although a device for preparing coa...
