Abstract

The invention discloses a structure and method for preparing a composite coating through electric spark multichannel deposition, and belongs to the technical field of electric spark deposition. The structure comprises a pulse power supply and a plurality of discharge circuits connected to the pulse power supply in parallel. Each discharge circuit comprises a diode and a capacitor which are connected in series. The anode of each diode is connected with the positive electrode of the pulse power supply. One end of each capacitor is connected with the cathode of the corresponding diode, and the other end of each capacitor is connected with the negative electrode of the pulse power supply. A to-be-processed substrate is connected with the negative electrode of the pulse power supply. A plurality of discharge channels are generated during one-time pulse discharge to perform transition deposition of materials, and corresponding circuit elements and protection elements are arranged, so that the coating preparation quality of each deposition electrode is ensured, multi-point synchronous deposition preparation of a multi-layer film or a composite coating on the surface of a part is realized, and the surface coating of the part is low in roughness and high in quality.

Description

Technical field [0001] The present invention relates to the field of electric spark deposition techniques, and more particularly to a structure and method for preparing a composite coating in a multi-channel deposition of an electric fire. Background technique [0002] The electrical spark deposition technique is to melt or gasify the electrode material to melt or gasify the electrode material using the instantaneous high temperature generated between the pole of the power supply pole (part surface and electrode), so that the melted electrode material is in electric field power, electromagnetic force, gravity. Under the action, the transition is deposited to the surface of the part, and the desired deposition layer is generated on the surface of the part, so that the surface quality and hardness of the part can be improved, and the repair and removal of the surface of the part can be improved. [0003] In the prior art, the electric spark deposition of the composite coating is pe...
