摘要
Various unipolar DC pulse waveforms were selected to find the factors for controlling of the anodized titanium surface morphology. The current density, frequency and duty were ranged from 50 mA/cm(2) to 750 mA/cm(2), from 100 Hz to 400 Hz and from 10% to 50%, respectively. Increase of duty from 10% to 50% at 100 Hz in 0.1 M KOH provides larger pores - from 0.13 mu m to 0.19 mu m in average for 50 mA/cm(2) and 0. 15 mu m to 0.24 mu m for 750 mA/cm(2). On the other hand increase of frequency from 100 Hz to 400 Hz at 50% duty provides smaller pores - from 0.19 mu m to 0.17 mu m for 50 mA/cm(2) and 0.24 mu m to 0.17 pm for 750 mA/cm(2). Both duty and frequency are important factors to control the anodized titanium surface morphology.
