technical field [0001] The invention relates to the technical field of thermoelectrochemical oxidation, in particular, the invention relates to a novel thermoelectrochemical oxidation device and a control method. Background technique [0002] Thermoelectrochemical oxidation is a new surface treatment technology that has developed rapidly at home and abroad in recent years. It is developed on the basis of anodic oxidation, also known as micro plasma oxidation, plasma thermoelectrochemical oxidation, plasma enhanced electrochemical oxidation. Surface ceramicization, etc. Thermoelectrochemical oxidation uses a higher working voltage, the valve metal workpiece is used as the anode, and the electrolytic cell is used as the cathode.

In the discharge area, under the a...

AI Technical Summary

Problems solved by technology

[0003] The prominent feature of thermoelectrochemical oxidation is that the surface hardness of the material is greatly improved, and it has good wear resistance, heat resistance, corrosion resistance, and insulation performance. However, its power supply needs to be customized, and the voltage is required to be between 300-700V, especially During thermoelectrochemical oxidation, the valve metal workpiece, electrolytic cell and electrolyte are all conductive, which consumes a lot of energy

The performance of the material after thermoelectrochemical oxidation is greatly improved, and it should be widely used. However, in reality, the products of this process have not been widely used. The main reason is that the process cost is high. Specifically, the power supply is valve metal workpiece, electrolytic The electrolyte of the battery and the entire electrolytic cell provides high-voltage power supply, which consumes a lot of electricity, and needs to maintain the temperature of the electrolyte between 10°C and 50°C. It needs to use a cooling system to cool the electrolyte, which consumes a lot of cooling power, so the cost is high. high

However, in order to achieve the effect of arc discharge, a high-voltage power supply must be applied, and the electrolyte needs to be cooled to prevent the spark discharge from getting out of control. Therefore, this is a problem that has not been able to be overcome in this field, and the promotion and application of the industry has not achieved breakthrough progress.
