Özet
As material science is integrated into medical science as in other fields, the variety, development and usage areas of biomaterials increase. One of the biomaterials in this variety is NiTi alloys. This study was focused on the coating of TiO2 layer by using the method of Micro Ark Oxidation with the aim of the improvement of surface and mechanical properties of Shapedmemory and bio material NiTi alloy. Structural properties of the coatings were analysed by of SEM and XRD. In vitro ability was investigated by soaking the coated NiTi samples in simulated body fluid (SBF) at temperature 37 degrees C for various time periods. After soaking, Ni+2 release was applied to the media where coated and uncoated shape-memory NiTi samples are available, and its control was made by means of ICP-MS device. The results also show that Toxic and carcinogenic effects of Ni+2 release is significantly reduced by the TiO2 coating. Thus, it is observed that the properties that limit the use of NiTi alloys has been substantially fixed by MAO coating. It was found that the bioactive properties of the TiO2 coated NiTi substrate increased by MAO method and at the end of the 72 hour, there was no statistically any cytotoxicity in cell viability compared to the NiTi substrate.
