Abstract

The invention discloses an ultrasonic micro-arc oxidation device and an ultrasonic micro-arc oxidation method thereof. The ultrasonic micro-arc oxidation device comprises an electrolytic tank, a power supply and a cooling water tank, wherein the electrolytic tank is placed in the cooling water tank and is electrically connected with the power supply. The ultrasonic micro-arc oxidation device further comprises an ultrasonic signal generator and an ultrasonic transducer, wherein the ultrasonic signal generator is electrically connected with the ultrasonic transducer which is placed in the electrolytic tank. Ultrasonic wave is added in the micro-arc oxidation process by the ultrasonic transducer to improve the mass transfer efficiency and the quality of a ceramic layer, increase the heat transmission coefficient and facilitate the heat transmission, therefore, the heat transmission efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of metal material surface processing, in particular to an ultrasonic micro-arc oxidation device and an ultrasonic micro-arc oxidation method thereof. Background technique [0002] Micro-arc oxidation, also known as plasma oxidation, is to grow a continuous and uniform ceramic film on the metal surface in situ through high pressure and high temperature in the micro-arc discharge area. The metal-based ceramic film layer has excellent performance, has the advantages of corrosion resistance, wear resistance, biological activity and high hardness, and is widely used in aerospace, machinery, textile and medical equipment and other fields. At present, the electrolytic cells of common micro-arc oxidation devices are generally in the shape of cubes, cuboids, and cylinders. The entire electrolytic cell is placed in a cooling water tank, and the upper and lower parts of the cooling water tank are respectively equipped ...
