Oxidation power supply is a device that utilizes high-frequency voltage and arc discharge to form an oxide film on the surface of metals, with many advantages and applications. This article will introduce the principle, characteristics, classification, and application of oxidation power sources.
The principle of oxidation power supply is to enhance the oxidation reaction on the metal surface by using high-frequency voltage and arc discharge on the basis of ordinary anodizing, thereby forming a dense, uniform, and high hardness oxide film. This oxide film can improve the corrosion resistance, wear resistance, insulation, and anti-static properties of metals, as well as improve the appearance and color of metals.
The characteristics of oxidation power supply include the following:
There are three output methods: constant current, constant voltage, and disturbance free conversion, which can be selected and adjusted according to different workpieces and process requirements to ensure the stability and accuracy of output voltage and current.
Adopting high-frequency switching technology, it has high efficiency, small size, light weight, low noise, good heat dissipation, and long service life.
By adopting an intelligent control system, it can achieve functions such as automatic detection, automatic protection, automatic compensation, and automatic recording, which is convenient for operation and management.
Adopting modular design, it can be combined or split as needed to adapt to different production scales and venues.
The classification of oxidation power sources mainly includes the following types:
According to the output waveform, it is divided into DC oxidation power supply and AC oxidation power supply. DC oxidation power supply outputs DC voltage and DC current, suitable for general anodizing processes; The AC oxidation power supply outputs AC voltage and AC current, suitable for special anodizing processes such as hard anodizing and micro arc oxidation.
According to output power, it is divided into low-power oxidation power sources and high-power oxidation power sources. Low power oxidation power supply with output power below 10kW, suitable for small or medium-sized workpieces; The high-power oxidation power supply has an output power of over 10kW and is suitable for large or heavy workpieces.
According to output frequency, it is divided into low-frequency oxidation power supply and high-frequency oxidation power supply. The output frequency of the low-frequency oxidation power supply is below 50Hz, suitable for low-temperature or low-voltage anodizing processes; The output frequency of the high-frequency oxidation power supply is above 50Hz, suitable for high-temperature or high-voltage anodizing processes.
Oxidized power sources have a wide range of applications, including aerospace, automotive, mechanical, printing, medical, communication, and many other fields. By using an oxidation power supply, various colored and functional oxide films can be formed on the surface of metals, thereby improving their performance and aesthetics. For example:
