Abstract
The primary aim of this study is to observe the influence of an applied voltages and a concentration of electrolyte on anodic oxide layer properties such as morphology, wettability and microstructural. First, sample was anodised under different voltages ranging from 10-40 volts in 0.1M H2SO4/0.075wt% HF. Anodised samples were characterised by Scanning Electron Microscope (SEM) and X-ray Diffraction technique (XRD). It was observed that an applied voltage at 20 volts, an interconnected pore network can be fabricated. Second, sample was prepared in 0.1M H2SO4 with the concentration of HF range from 0.075 -0.5 wt% at the applied potential of 20 volts. Based on experimental results, the microstructure of anodic oxide layers depends strongly on the formation potential and the HF concentration. Nanopores can be formed under a range of experimental conditions. Moreover, it was found that titanium oxide nanotube arrays are formed in 0.1M H2SO4/0.4wt% HF. XRD patterns of anodised samples showed the tubes crystallised in a coexistent of titanium and titanium oxide phases. The anodised surfaces are more hydrophobic than the untreated surface. © 2010 International Federation for Medical and Biological Engineering.
