Multifunctional layers formation was performed to improve the biocompatibility of NiTi shape memory alloys for further long-term implant applications. The surface of NiTi alloy was covered by thin rutile film by autoclaving to improve chemical contact between deposited material and substrate. The electrophoretic deposition processes (EPD) of β-tricalcium phosphate (β-TCP) was applied. The particle size distribution of β-TCP (with dominant size ca. 500nm) in the colloidal suspension and after deposition was estimated. Calcium, phosphorus and oxygen distribution on the surface of NiTi was analyzed. A thin film consisted of phosphates groups was found.
