Finishing method of Titanium for human body


Dear lady or Gentleman

Titanium has been used a join parts to bones inside of body. This titanium material would be finished at certain method which should be harmless in body. If you know what kind finishing is used for this purpose, please let me know. Your kind advice would be highly appreciated.

Thank you

Aragonite is a calcium carbonate mineral that has been applied as a ceramic coating to titanium implants. This coating is chemically similar to common tooth enamel and can be made very rough to promote tissue adhesion and knitting to bone.

For adhesion to the bone, pure titanium is quite good, but you have to rough it up. Hydroxyapetite has also been accepted by the FDA. For wear surfaces, ion implantation is necessary and FDA accepted -- titanium is not a good wear material, and should not be used in a wear application in the body without surface treatment.
