Chemistry of Anodization Part2

This will probably be my last post as my co-op has ended. It was a valuable learning experience and I am sorry that I did not post more but I didn't want to be redundant. I hope this will benefit others in some way. If anyone who visits this site has any questions, feel free to ask.

I have found that each anodization is unique which is due to deviations of concentration in solution preparation and temperature. Such can be found in this research paper:

Though I can't say that all of my anodizations went perfect....
Unfortunately this happened due to the anode stirp comming in contact with the stainless steel screw. I am not sure how long it went on but the high current was enough to burn through the fiberglass circuit board.

Happy Anodizing!
