Abstract

An anodic oxidation device, which includes: an electrolytic cell, which is a structure with both ends connected, one end of the electrolytic cell is connected to a cathode plate, and an inlet pipe and an outlet pipe are provided on the surface of the electrolytic cell; a mold, one end of which is connected to the electrolytic cell The other end of the tank is connected, and the other end of the mold is connected with the product; electrolyte, which flows in the electrolytic tank and the mold; power supply, whose positive pole is connected to the mold, and the negative pole of the power supply is connected to the cathode plate. In addition, the present invention also provides an anodic oxidation method, the steps include: injecting the electrolyte into the electrolytic cell from the inlet pipe, the electrolyte flows to the two ends of the product and the cathode plate respectively and generates A certain impact pressure; the power supply is connected, and the electrolyte is anodized to the product through the mold; the gas and heat generated during the anodization of the above product are quickly discharged from the outlet pipe along with the electrolyte .

Description

【Technical field】 [0001] The invention relates to an anodic oxidation device and a method thereof, in particular to a device and a method capable of obtaining an anodic oxidation film on a partial surface of a product. 【Background technique】 [0002] Anodic oxidation is the electrochemical oxidation of metals or alloys. Its principle is to use metal or alloy parts as anodes, and use electrolysis to form oxide films on the surface. The metal oxide film changes the surface state and properties, such as surface coloring, improves corrosion resistance, enhances wear resistance and hardness, and protects the metal surface. [0003] There are a large number of micropores in the thin layer of oxide film, which can absorb various lubricants, and is suitable for manufacturing engine cylinders or other wear-resistant parts; the film micropores have strong adsorption capacity and can be colored into various beautiful and bright colors. Non-ferrous metals or their alloys (such as alumi...
