Anodization of aluminum alloys and its process parameters has been established based on material characteristics of conventional DC cast and hot rolled materials. There has been almost no detailed investigation to elucidate anodization behaviour of twin roll cast aluminum sheets. In the present study, twin roll casting was employed to produce materials exhibiting equivalent performance to those of conventional counterparts during anodization processes. New processing frames in chemical and electrochemical steps of anodization has been tested. Evolution of surface coating, associated pore size and surface features has been correlated with different combination of anodization parameters applied and compared with those of DC cast sheets. Optical microscope and FEG were used for characterization studies.
