This work presents the nanoindentation and XPS results of a newly-developed biomaterial of titanium TNZ alloy after different surface treatments. The investigations were performed on the samples AR (as received), EP (after a standard electropolishing) and MEP (after magnetoelectropolishing). The electropolishing processes, both EP and MEP, were conducted in the same proprietary electrolyte based on concentrated sulfuric acid. The mechanical properties of the titanium TNZ alloy biomaterial demonstrated an evident dependence on the surface treatment method, with MEP samples revealing extremely different behavior and mechanical properties. The reason for that different behavior appeared to be influenced by the surface film composition, as revealed by XPS study results displayed in this work. The increase of niobium and zirconium in the surface film of the same titanium TNZ alloy after magnetoelectropolishing MEP treatment is meaningful and especially advantageous considering the application of this alloy as a biomaterial.
这项工作展示了一种新开发的钛TNZ合金生物材料在不同表面处理后的纳米压痕和XPS结果。研究是在AR（原样）、EP（标准电解抛光后）和MEP（磁电解抛光后）样品上进行的。电解抛光过程，即EP和MEP，均在基于浓硫酸的同一专利电解液中进行。钛TNZ合金生物材料的力学性能明显依赖于表面处理方法，MEP样品表现出截然不同的行为和力学性能。如本工作中XPS研究结果所示，这种不同行为的原因似乎受表面膜成分的影响。考虑到该合金作为生物材料的应用，磁电解抛光MEP处理后同一钛TNZ合金表面膜中铌和锆的增加是有意义的，且特别有利。
