PEO on aluminum

Q. Hello:

I am a university student. I am searching some information about a method to protect aluminium named PEO (Plasma Electrolytic Oxidation). If there is any help available, it will be gratefully appreciated.

Thanks.

A. Hi,
PEO means plasma electrolytic oxidation.
This process is applied on light metals like aluminium, titanium, magnesium, ...
This process needs a nice power supply with min. 600 volt output in bipolar and constant current mode.
This process has 2 issues:
1- electronics hardware (how to apply voltage and current applied) that are needed.
2- electrolytic chemicals
