The invention relates to the technical field of electroplating, in particular to a composite powder electroplating device. During operation, copper block and electroplating solution are added through the feeding plate, composite powder is added into the hopper, the anode plate is connected to the positive pole of the power supply, so that the copper block can precipitate cations, and the cathode plate is connected to the negative pole of the power supply to reduce metal cations, the motor operates, and the scraper Under the action of the spring, it rotates and fits the rotating plate. The composite powder on the rotating plate rolls under the action of the scraper, and the copper block is scraped and cut by the scraping mechanism to increase the concentration of copper ions. At the same time, the copper block is in the extrusion process. , No. 1 air bag and No. 2 air bag generate gas to supply the blowing pipe. During the flow of the electroplating solution, blowing air prevents the composite powder from falling between the cathode plate and the anode plate, so that the composite powder can be fully electroplated on the side of the cathode plate. In the present invention, the concentration of copper ions in the electroplating solution is increased by making copper precipitate copper ions faster, and at the same time, the composite powder rolls and circulates in the rotating device to ensure sufficient electroplating and a uniform and compact coating.
Description
technical field [0001] The invention relates to the technical field of electroplating, in particular to a composite powder electroplating device. Background technique [0002] Metal-coated composite powder is a new type of multi-phase composite powder metallurgy material. It has many varieties and unique properties. It has been widely used in defense industry, machinery manufacturing, chemical industry and other fields. According to different core-shell structures, metal-coated composite powders can be roughly divided into three types, metal-carbon materials, metal-ceramic materials, and metal-metal materials. The preparation methods of metal-coated composite powder are usually as follows: ball milling method, impregnation method, sol-gel method, co-precipitation method, electroless plating and electroplating method, etc. The ball milling method is simple, and the content of metal in the powder is easy to control, but it is difficult to form a coated composite powder, espec...
