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 …
