Plasma power supply

company has provide this service to two costumers locally with the value of 8000 USD.

A plasma power supply is and electrical power source which generates an appropriate electrical signal regarding its frequency, voltage and power to perform Plasma Electrolytic Oxidation (PEO) processes. PEO or Micro Arc Oxidation is an electrochemical process of oxidation that is performed by creating micro-discharges on the surface of components immersed in an electrolyte. The process is applied to Aluminum, Titanium, and Magnesium to grow a dense, ductile nano-ceramic oxide layer that improves mechanical, wear, thermal, dielectric, and corrosion properties. PEO process uses a controlled high-voltage alternating current that is applied to a metal part submerged in an electrolytic bath. Due to the high voltage and current, intense plasma is created on the surface of the metal. This plasma oxidizes the surface of the part and grows a nano-structured ceramic oxide layer from the substrate material. The oxide film is produced by subsurface oxidation. As a result, the process can produce very thick coatings of varying porosity. The process can readily grow coatings up to 250 microns thick, and ongoing research is showing feasibility of coating thicknesses of up to 500 microns. ALFA Co. produces plasma power supply in the range of power up to 20 kW, unsymmetrical controllable bipolar square voltage from 0 to 800 V, variable duty cycle from 10 to 90 percents, Constant Current (CC) and Constant Voltage (CV) mode of operation, and other useful parameters to control PEO processes.

it uses in coating process. PEO coating uses to coat aluminum oxide, titanium oxide, magnesium oxide.
