200A200V air-cooled hard oxidation power supply

Single pulse micro-arc oxidation power supply

The micro-arc oxidation process, also known as plasma electrolytic oxidation, micro-plasma oxidation, etc., refers to a method of using arc discharge to enhance and activate the reaction at the anode on the basis of ordinary anodic oxidation, thereby forming a high-quality reinforced ceramic film on the surface of workpieces made of metals such as aluminum, titanium, magnesium and their alloys. It is a method of applying voltage to the workpiece with a dedicated micro-arc oxidation power supply, so that the metal on the surface of the workpiece interacts with the electrolyte solution, forming micro-arc discharge on the surface of the workpiece, and under the influence of high temperature, electric field and other factors, a ceramic film is formed on the metal surface, thereby achieving the purpose of strengthening the workpiece surface.

How can customers choose high-frequency rectifiers correctly and reasonably?

Choosing electroplating rectifier power supply equipment also requires knowledge, and three requirements must be met:

1: To comply with the specifications required by the electroplating process, including the power size of the power supply, waveform indicators, and electrical performance Adjustable range of current voltage value, etc;

2: It is the reliability performance of the power supply itself, which mainly refers to the rationality, safety, and circuit characteristics of the structurePoint, cooling method, etc;

3: Consider the cost-effectiveness of its price.

Note: If the customer is not familiar or unsure, they can contact customer service for consultation
