Description

Device and method for preparing micro-anode by using localized electrochemical deposition additive manufacturing
Technical Field
The invention belongs to the field of 3D printing technology and electrochemical deposition, and particularly relates to a device and a method for preparing a micro anode by using localized electrochemical deposition and additive manufacturing.
Background
3D printing techniques, also known as additive manufacturing techniques, are techniques that enable manufacturing by progressive accumulation of material based on discrete or stacked principles. The 3D model of the formed part is cut into a series of thin slices with certain thickness by using a computer, each layer of thin slices is manufactured from bottom to top by using 3D printing equipment, and finally, three-dimensional solid parts are formed by superposition. The manufacturing technology does not need a traditional cutter or a mould, can realize the manufacturing of complex structures which are difficult or impossible to process by the traditional process, can effectively simplify the production process and shortens the manufacturing period. As a comprehensive application technology, 3D printing integrates leading edge technical knowledge in many aspects such as digital modeling technology, electromechanical control technology, information technology, material science and chemistry, and has very high technological content.
Localized electrochemical deposition (LECD) is a typical maskless micro-electrochemical additive manufacturing technique that uses ultra-fine inert anode tips to create a very localized electric field to induce electrodeposition on the cathode, forming micro-scale and nano-scale 3D features. In LECD, both the anode and the cathode are immersed in the electrolyte with a constant small inter-electrode gap, and the anode is precisely spatially moved relative to the cathode (or the formed deposit) in a pre-designed path. Meanwhile, metal electrodeposition occurs in a local area directly under the tip of the anode, creating a three-dimensional microstructure. At present, the common LECD micro-anode is a platinum wire disc electrode wrapped by a capillary glass tube, and because the LECD is often formed into a microstructure with very small dimension, an inert metal wire with very small diameter needs to be packaged in the capillary glass tube, and in the process, the diameter of the inert metal wire is very small and the hardness is reduced, so that a great challenge is brought to the preparation of the micro-anode, and meanwhile, the packaged electrode needs to be ground into an end face with very high flatness requirement by sand paper, a grinding instrument and the like, so that great difficulty is brought to the preparation of the micro-anode.
