Electrochemical Thinning for Anodic Aluminum Oxide and Anodic Titanium Oxide

open access: yesBulletin of the Korean Chemical Society, 2012
For given electrolytes, different behaviors of anodic aluminum oxide (AAO) and anodic titanium oxide (ATO) during electrochemical thinning are explained by ionic and electronic current modes. Branched structures are unavoidably created in AAO since the switch of ionic to electronic current is slow, whereas the barrier oxide in ATO is thinned without ...
