Purpose: The aim of this study was to make nanomesh on the surface of titanium by potentiostatic technique which was done at the suitable potential level.
Methods: In order to find the suitable potential level, use a 25℃ NaCl, NaOH and NH4F solution of 1 M and 5M as supporting electrolyte, working electrode(positive potential) was contact to the titanium specimen and counter electrode(negative potential) was contact to the Pt substrate. At the transpassive potential which was observed by potentiostatic technique, potentiostatic technique was done for 2hours.
Results: As a result, 1 M NaOH solution was suitable as a supporting electrolyte, potentiostatic technique used a 25℃ NaOH solution of 1 M for 2hours, nanomesh was formed.
Conclusion: The potentiostatic technique was used 25℃ NaOH solution of 1 M and 5 M as supporting electrolyte for 2hours. Nanomesh was built more uniform and fine in 1 M NaOH solution than 5 M NaOH solution.
