Main principle: The micro-arc oxidation technology is to put the metal product of which oxide has the ceramic structure into slightly alkaline electrolyte exclusive of heavy-metal ion, with specific electric field to make the metal atom in the surface of product bond with oxyanion in electrolyte and form a ceramics layer in the surface which can bond with the product in the way of micro-metallurgy. According to the difference of technological conditions and application scope of work piece to be settled, this ceramic layer can improve the anticorrosion, antifriction, galling resistance and insulation of metal. The key point of micro-arc technology is the power supply. The main function of the power supply is to provide and control the electric field with sufficient density energy and optimum distribution as well as automatically detect and control procedure parameter in the production process of micro-arc oxidation treatment. Features of power supply: 1. The adoption of advanced technology of switching power supply, small in volume and high in efficiency 2. It is automatically controlled by single-chip. 3. The width of positive and negative going pulse can be adjusted and the duty ratio can be adjusted within 5~95%; The range of commutating frequency for the pulse is 10-2000Hz; Frequency, positive and negative current and ratio of positive and negative pulse can be continuous controlled independently within wide adjustable range. 4. It can be equipped with technology data management system to realize the trace management of technology 700V 750V 100A 200A Single Pulse Micro Arc Oxidation Power Supply / Mao / Peo Power Supply 700V 750V 100A 200A Single Pulse Micro Arc Oxidation Power Supply / Mao / Peo Power Supply Package &shipping 700V 750V 100A 200A Single Pulse Micro Arc Oxidation Power Supply / Mao / Peo Power Supply
