Description

Electrochemical deposition integrated device based on fused deposition preparation mask
Technical Field
The invention belongs to the technical field of electrochemical additive manufacturing, and particularly relates to an electrochemical deposition integrated device for preparing a mask based on fused deposition.
Background
Electrochemical deposition has a long research history, the theory of the electrochemical deposition is the basis of traditional industrial processes such as metal electrolytic smelting, electroplating and electroforming, and the electrochemical deposition has great application in the aspects of guiding the manufacturing of nano electronic devices and developing novel materials with unconventional performance. In recent years, with the continuous deepening of relevant theories and experimental researches, the electrochemical deposition technology is greatly developed, and more deposition methods are adopted, which mainly comprise direct current deposition, pulse electrodeposition, jet electrodeposition, composite electrodeposition and the like.
The main principle of electrochemical deposition is that a conductive metal material is used as a cathode, a solution (which can be a single metal ion solution or a mixed solution of multiple metal ions) containing a substance to be deposited with a certain concentration is contained on the surface of the cathode, the solution is contacted with an anode to form a loop, and the metal ions in the deposition solution are reduced into atoms on the surface of the cathode by controlling the temperature, the pH of the deposition solution, the deposition current and the potential so as to be deposited on the surface of the cathode, so that a required film or a coating with a certain thickness is prepared. The film or the coating is prepared by electrochemical deposition, and has the following advantages: uniform films or coatings can be deposited on a variety of complex substrates, usually at room temperature or slightly above; the amount of the sediment is controlled by Faraday's law, and the thickness, chemical composition, structure and the like of the sediment layer can be accurately controlled by controlling the process conditions; the method has the advantages of less equipment investment, simple process, easy operation, environmental safety and flexible production mode, and is an efficient and economic additive manufacturing method.
The fused deposition technology is that a three-dimensional model is constructed by CAD modeling software, and then is sliced and scribed by a computer and converted into corresponding geometric data; various hot-melt filamentous materials are adopted as processing substances, the processing substances are input into a spray head through a filament supply device, the spray head is melted by a high-temperature heating device, and then the processing substances are sprayed out from a tail end nozzle; the computer controls the nozzle to move according to the converted corresponding geometric data so as to print out the required shape.
The spray electrochemical deposition is mainly characterized in that a certain voltage is applied between a substrate (cathode) and a nozzle (anode), simultaneously, a deposition solution is sprayed to the surface of the substrate at a high speed, and in a spray coverage area, a cathode and an anode form a loop through the deposition solution, so that the electrochemical deposition is generated on the surface of the substrate. When the electrodeposition is sprayed, the electrodeposition liquid is sprayed onto the surface of the cathode workpiece from the anode nozzle at a high speed with a certain flow rate and pressure, so that the mechanical activation is carried out on the coating, and the thickness of the diffusion layer is effectively reduced.
The Chinese patent with the application number of 201910643332.4 discloses an electrochemical 3D printing device and a printing method for a metal matrix composite part. The method leads out a metal wire through a nozzle, and prints the required entity layer by layer in a mode of dissolving and depositing in electroplating solution. The method improves various properties of a single metal material and reduces the production cost of the metal composite material part. However, the sharpened wire used in the deposition process is troublesome to manufacture, and the moving speed is not well controlled when the sharpened wire is dissolved and deposited.
The Chinese patent with the application number of 201710021228.2 discloses a manufacturing method of a structural circuit integrated component based on a fused deposition modeling technology. According to the method, a three-dimensional model is built, the position of a conductive channel is reserved, the double-nozzle fused deposition machine tool is used for printing layer by layer in a circulating manner to complete the formation of a part entity, and finally the entity is placed into a copper plating solution for electroplating, so that the reserved channel is filled with metal copper. The method can realize the integrated printing of the complex three-dimensional circuit in the structural component, and has simple process. However, the method can only realize electroplating of a small conductive channel in the member, and the whole entity is put into the plating solution, so that the morphology and quality of the plating layer are not convenient to control, and the efficiency is low.
Chinese patent No. 201910160455.2 discloses a jet electrodeposition 3D fine metal additive manufacturing device. The method uses a micro-anode platinum electrode to guide the position of the conductive deposition and control the flow rate of the plating solution, so that the metal ions are deposited layer by layer on the substrate. The platinum electrode of the micro anode in the device can generate local high current density, so that the material increase manufacturing speed of the micro three-dimensional component is accelerated, and the change of the construction structure can be realized. However, this apparatus can only process a fine three-dimensional member, and cannot process a structure having a large surface shape.
