Hydrophilicity, Low current density, Two-step anodization


The anodized films were performed by two step anodization. The main objective of this study was to investigate the effect of different low current density by two step anodization on the anodizing behavior, surface morphologies, surface roughness, surface species and hydrophilic property of the anodized films. The FESEM and AFM were used for the analysis of the surface morphology and roughness of the anodized films. The surface roughness was obtained after anodization. The XPS was used for study the surface species of the anodized films. The results showed that the OH group increased after anodizing process at low current density of 0.5 mA cm-2 in 1 M H3PO4 + 80% V/V C2H5OH. Hydrophilic property was measured by contact angle measurement. It was seen that the anodized films surface became hydrophilicity. Therefore, the increase in both OH groups and surface roughness could enhance the hydrophilicity to the anodized films, which are two important factors for improving osseointegration in order to apply to dental implant application.
