The aim of the present research is to convert bioinert surface of NiTi to bioactive and biocompatible surface. In order to develop a bioactive and corrosion resistant film on NiTi, electrophoretic deposition process was done and TiO2 particles were deposited on the NiTi surface. Suspensions including TiO2 particles were prepared using a mixture of acetone and n-butanol (0%, 30%, 60%, 80% and 100% acetone) without using any dispersant.  Sedimentation test was used to characterize the suspensions. SEM investigations on surface morphology of coatings shows depositing within 0% acetone cause to crack-free and dense coating with relatively coarse grains and high corrosion resistance.
