  • Scratch Behavior Of Aluminum Anodized In Oxalic Acid
    Dec 15, 2021  It may be noted that the anodization of aluminum in oxalic acid solution is possible within a large potential window (potentials lower than 5 V and higher than 60 V have been reported) , . However, the pore size of anodic alumina increases significantly with the increase in applied potential . The presence of large pores is detrimental for applications such as corrosion protection due to easy
