Supercapacitance behavior of porous oxide layer grown on 302 type stainless s…

Abstract. Nano-porous oxide layers on the surface of 302-type stainless steel were synthesized by galvanostatic anodization process carried out at two current densities, 7 and 15 mA cm
-2 for the time periods of 15 and 30 min. A relatively thinner (~300 nm) and compact oxide layer formed when anodization was performed at a current density of 7 mA cm-
2. However, with increase in anodization…
