Abstract

The invention provides a low-noise micro-arc oxidation device, relating to a micro-arc oxidation device. The device aims at solving the problem of the existing micro-arc oxidation device that the noise is large in the process of micro-arc oxidation. A box body is internally provided with a barrel-shaped stainless steel electrolytic bath with a cooling water tank; a stainless steel shield plate ispositioned on the box body; a box cover is positioned on the stainless steel shield plate; an interlayer of the box body and the box cover is internally filled with acoustic insulating materials; theperiphery of the barrel-shaped stainless steel electrolytic bath is paved with soft acoustic materials; a gas discharge pipeline is communicated with a gas discharge chamber; a gas pipe is communicated with the barrel-shaped stainless steel electrolytic bath; a cooling water inlet pipe and a cooling water outlet pipe are communicated with a cooling water sleeve of the barrel-shaped stainless steel electrolytic bath; a solution discharge pipe is communicated with the barrel-shaped stainless steel electrolytic bath; the two ends of a micro-arc oxidation cathode and the cathode of a micro-arc oxidation electric power source are connected with the outer wall of the barrel-shaped stainless steel electrolytic bath; and the two ends of a micro-arc oxidation anode and the anode of the of the micro-arc oxidation electric power source are connected with a work piece. The device can greatly reduce noise dissemination intensity and ensure the stability of a micro-arc oxidation technology.

Description

technical field [0001] The invention relates to a micro-arc oxidation device, which belongs to the technical field of metal material surface processing. Background technique [0002] Micro-arc oxidation, also known as plasma oxidation, is a new technology for in-situ growth of oxide ceramics on the surface of Al, Mg, Ti and other non-ferrous metals and their alloys. It is developed on the basis of traditional anodizing, but it breaks through the voltage limit of anodizing, and the applied voltage is higher. This technology is to put Al, Mg, Ti and other metals into the conductive solution, and immediately form a thin layer of oxide insulating film on the metal surface after electrification. As the voltage increases, the potential at the interface between the electrolyte and the metal sharply Increase, resulting in the breakdown of the weak part of the formed oxide insulating film layer, and the phenomenon of micro-arc discharge occurs. Through the generation of high temper...
