Surface Modification of Vacuum Plasma Sprayed Titanium Coating via Two Different Treatments
Vacuum plasma sprayed (VPS) Ti coatings were deposited and their surface modification processes were performed by NaOH solution treatment and alkali-heat-calcification respectively. The simulated body fluid test indicated that apatite was formed on the surfaces of Ti coatings. A net-like structure was observed on the surfaces of Ti coatings treated by alkali-heat-calcification, whose bioactivity is much better than that treated by NaOH aqueous solution simply.
