Preferential oxidation of Ti on NiTi alloy surface has been observed and was consistent with the experimental result and the free energy of formation A G?(298K) of NiO, TiO, TiO2. Mulliken population and the partial density of state analysis showed that the interaction between Ti and O atoms was mainly donated by O 2p and Ti 4s orbital and O 2p and Ti 3d, 4s, 4p hybridization orbital. The electron structure in NiTi bulk material was not altered during 62 molecule adsorption process and the surface passivation oxide formation.

进一步对钛与氧之间相互作用本质的研究表明，O 2p轨道和Ti 4s轨道以及O 2p轨道和Ti 3d 4s 4p杂化轨道间的相互作用是NiTi合金表面氧分子吸附的驱动力，在此过程中，NiTi合金的体相结构没有发生变化，从而保证了其一系列力学性能和形状记忆特性在表面氧化后不发生明显的变化，使表面改性的工作可以安全、可靠的完成而不影响其植入人体后发挥正常的生理功能。

The electron structure in NiTi bulk material was not altered during O〓 molecule adsorption process and the surface passivation oxide formation. Thus the mechanical properties and shape memory effect would not change after NiTi alloy surface oxidation. Stable microstructure demonstrates reliability of implant material.
