Plasma Electrolytic Oxidation with Alternating Current

Plasma Electrolytic Oxidation with Alternating Current and Asymmetric Electrodes For this project we developed a Plasma Electrolytic Oxidation (PEO) process that facilitates the coating of two light alloy parts simultaneously using alternating current. The coatings are as homogenous as conventional PEO processes with AC, but with double the process speed. The project builds on a conventional AC power supply by Aixcon, but adds a superimposed controller that adjusts the current according to the coating thickness. The process was developed together …

PEO Anwendung im Labor


Aixcon offers DC and AC power sources as well as microwave generators for a variety of coating processes. Aixcon in particular also supports processes that place high demands on the power supply, such as those with high pulse rates or special pulse shapes. Microwave Coating Microwaves (915 MHz / 2.45 GHz / 5.8 GHz) are a good source for plasma excitation. Microwaves can achieve higher plasma densities than RF or DC excitation. Aixcon’s microwave generators are deployed in various plasma …
