Abstract

The invention discloses a micro-arc oxidation synchronous auxiliary electromagnetic field device, and belongs to the technical field of micro-arc oxidation devices. The device aims to solve the technical problems that an existing micro-arc oxidation device is low in machining efficiency, and sometimes ablation is prone to happening in the micro-arc oxidation film growing process. The device further comprises an electromagnetic field assembly. The electromagnetic field assembly is composed of a hollow pipe and N turns of coils wound around the outer wall of the hollow pipe. The electromagnetic field assembly is arranged in a micro-arc oxidation tank. A workpiece is mounted in the electromagnetic field assembly and serves as an anode to be connected with the output positive pole of a power box. The micro-arc oxidation tank and the hollow pipe serve as a cathode to be connected with the output negative pole of the power box. The power box controls on-off of the hollow pipe and the coils. According to the device, an auxiliary synchronous electromagnetic field is additionally mounted to act on electrolyte micro-plasma, the growing rate of a micro-arc oxidation film layer can be further increased, and meanwhile the ablation defect appearing during film layer growing in the micro-arc oxidation process is avoided.

Description

Technical field [0001] The invention belongs to the technical field of micro-arc oxidation devices, and specifically relates to a micro-arc oxidation synchronous auxiliary electromagnetic field device. Background technique [0002] Micro-arc oxidation technology is a kind of surface ceramic modification technology. It is developed from ordinary anodization. It breaks through the limitations of the traditional anodizing current and voltage Faraday region, and increases the anode potential from tens of volts to several One hundred volts, using arc discharge to enhance and activate complex reactions such as electric field, physics, chemistry, and electrochemistry that occur on the anode workpiece. Micro-arc oxidation technology has the characteristics of simple process, high treatment efficiency, low cost and no pollution. The micro-arc oxidation ceramic film has abrasion resistance, corrosion resistance, high temperature impact resistance, good thermal stability, and its comprehen...
