Plasma electrolytic oxidation of an Al-Cu-Li alloy in alkaline aluminate electrolytes: A competition between growth and dissolution for the initial ultra-thin films
TL;DR: In this paper, it is proposed that, after the formation of a thin pre-existing film(∼ 1-2μm) on the alloy in less concentrated electrolytes, then thick coatings develop more rapidly in 32.g l−1 NaAlO2+1/g l/1 KOH, since the field assisted dissolution is only prevalent in extremely thin films and retreats quickly as the film thickens.

TL;DR: In this article, the plasma electrolytic oxidation process of aluminium alloys is investigated for two different current waveforms and it is shown that particular conditions may be established which strongly reduce the arcing that usually causes detrimental defects in the oxide layer for treatment time greater than typically 40-50min.
