AI Technical Summary

Problems solved by technology

[0003] In the prior art, the solution resistance in the electrolyte is relatively large, and the fluidity of the electrolyte is poor, which has an impact on the performance of the ceramic layer of thermoelectrochemical oxidation

In order to promote the circulation and uniformity of the electrolyte, the existing technology adds ultrasonic waves outside the electrolytic cell, which reduces the resistance of the solution accordingly, promotes the circulation and uniformity of the electrolyte, promotes the initial stage of thermoelectrochemical oxidation, and improves the surface of the workpiece. The performance of the ceramic layer, but the cost of ultrasonic is high, it is difficult to get practical application

Moreover, the power consumption of the prior art and the cooling power consumption of the electrolyte are large, resulting in high cost of workpieces for thermal electrochemical oxidation, which hinders the development and application of this field
