How to achieve large pores at titanium surface

September 8, 2008

Dear All, I am a PhD student working on titanium implants. i was able to produce porous titanium surface by using 1wt% HF+1M H3PO4.The pore sizes were 300-500 nm. I need pores larger than 2 microns. Could any one please give me any suggestions? Thanks

Try a mixture of 5% KOH + 5% H2O2. It will work slowly, perhaps 4-8 hours @ ambient temp.

Dear Toulou Shokuhf,

You have to suitably modify the pH, current density and treatment time to modify the pore size.
