It is mainly used for the micro-arc oxidation process.
Micro-arc oxidation, also known as micro-plasma surface ceramization technology, is developed on the basis of conventional anodization. It uses arc discharge to strengthen and activate the reaction occurring on the anode, so as to form a high-quality reinforced ceramic film on the surface of workpieces made of aluminum, titanium, magnesium and their alloys.
By applying voltage to the workpiece through a dedicated micro-arc oxidation power supply, the metal on the workpiece surface interacts with the electrolyte solution to generate micro-arc discharge. Under the combined effect of high temperature and electric field, a ceramic film is formed on the metal surface, achieving the purpose of workpiece surface strengthening.Performance
