Abstract

The invention provides a micro-arc oxidation hanger, which includes a hanging rod and a clamping mechanism arranged at the bottom of the hanging rod, a hook is provided on the top of the hanging rod, and the bottom of the hanging rod and the clamping mechanism adopt The shaft is connected by rotation, and the clamping mechanism adopts detachable bolts and nuts, which are fixedly connected through the bolts and nuts through the jumper connecting line holes on the aluminum alloy parts of the catenary, and on the connection surface of the hanger and the parts An elastic sealing ring is provided. The micro-arc oxidation hanger provided by the present invention is connected in a detachable threaded manner, which has the advantages of simple installation and disassembly and reusability; the elastic sealing ring is used to seal the contact point to prevent the electrolyte from entering and causing partial discharge Phenomenon, effectively improve the quality of micro-arc oxidation film.

Description

technical field [0001] The invention relates to the technical field of micro-arc oxidation racks, in particular to a micro-arc oxidation rack. Background technique [0002] Micro-arc oxidation is an emerging surface treatment method in recent years. Micro-arc oxidation technology can prepare a layer of oxide film with ceramic properties on the aluminum alloy and its surface, which can greatly improve the wear resistance and corrosion resistance of the aluminum alloy substrate. Micro-arc oxidation breaks through the Faraday region of anodic oxidation and enters the high-voltage discharge region. It is because of the high voltage in the micro-arc oxidation process that anodized racks cannot be used in the micro-arc oxidation process. If the contact is poor during the oxidation process, surface discharge will occur, the quality of the ceramic oxide film will be poor, and local ablation will occur, which will seriously affect the progress of micro-arc oxidation. At this stage...
