Porous anodic alumina has been produced on Al-0.5 wt% Mn substrate by single-step anodising at 50 V in 0.5 M oxalic acid at temperature ranged from 5°C to 25°C for 60 minutes. The steady-state current density increased accordingly with the temperature of oxalic acid. Hexagonal pore arrangement was formed on porous anodic alumina that was formed in oxalic acid of 5, 10 and 15°C while disordered porous anodic alumina was formed in oxalic acid of 20 and 25°C. The temperature of oxalic acid did not affect the pore diameter and interpore distance of porous anodic alumina. Both rate of increase of thickness and oxide mass increased steadily with increasing temperature of oxalic acid, but the current efficiency decreased as the temperature of oxalic acid increased due to enhanced oxide dissolution from pore wall. 2014-06-09T02:15:54Z 2014-06-09T02:15:54Z 2013 Article Journal of Nanomaterials, vol.2013, 2013, pages 1-8 1687-4110 http://www.hindawi.com/journals/jnm/2013/167047/ http://dx.doi.org/10.1155/2013/167047 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35193 en Hindawi Publishing Corporation |
