The Plasma Oxidation Rectifier from Gaohui Rectifier delivers 5A at 750V for thin ceramic mao coatings. This Plasma Oxidation Rectifier powers a wide range of oxidation racks with stable DC or pulsed output. Furthermore, the Plasma Oxidation Rectifier uses water cooled IGBT stages that hold tight output stability under full load. Consequently, oxidation shops rely on it for uniform, repeatable coatings. Moreover, surface-finishing facilities select this Plasma Oxidation Rectifier for its water cooled design and 5A 750V capacity that keeps deposition rates predictable. Consequently, production planners factor it into daily schedules without derating concerns.
Cooling: Water cooled | Application: Thin Ceramic MAO Coatings | Ripple: ≤5% | Interface: RS485/PLC
The 5A 750V rectifier is purpose-built for micro-arc oxidation, where the bath voltage climbs into the plasma range of several hundred volts. It grows hard ceramic oxide coatings on aluminum, magnesium and titanium alloys. For example, it coats engine components, aerospace parts and medical implants to over 100 microns. Furthermore, the high-voltage output sustains the micro-arcs that form dense alumina. Moreover, pulsed control refines pore structure and lowers energy use. In addition, the RS485, optional PLC port allows remote monitoring.
Moreover, this rectifier supports ramp-up profiles that prevent spark runaway on fresh parts. In addition, water-cooled cooling keeps output stable through long MAO cycles. Consequently, customers use it for wear-resistant, corrosion-protective ceramic coatings on light alloys. Moreover, operators appreciate the clear controls on this unit. Finally, the Gaohui service team responds quickly to spare-part requests, which keeps the line running.
