摘要

本工作的目的是改善cp-Ti 2级和β-钛合金TNTZ (Ti-29Nb-13Ta-4.6Zr)的表面性能，用于生物医学应用。采用喷丸强化和化学腐蚀相结合的复合表面处理方法。随后，对改性后表面的物理化学性质和形貌进行了分析。显微硬度测量表明，喷丸试样的表面硬度大大提高，达到与超细晶和纳米结构材料相似的水平。粗糙度测试和显微观察显示了显著的地形差异，这取决于所涉及的材料和改性过程。此外，本文还论证了基质和处理对润湿性的影响。研究结果证实了所设计的Ti 2级与TNTZ的杂交改性具有显著的生物医学应用潜力。

Tailoring Ti Grade 2 and TNTZ alloy surfaces in a two-step mechanical–chemical modification*

The aim of this work was to improve the surface properties of cp-Ti Grade 2 and β-Ti alloy TNTZ (Ti-29Nb-13Ta-4.6Zr) for biomedical applications. A hybrid surface treatment consisting of shot peening and chemical etching was conducted. Subsequently, the physicochemical properties and topography of the modified surfaces were analysed. Microhardness measurements of the shot-peened samples revealed a great increase in the surface hardness to the similar level as can be achieved for the ultrafine-grained and nanostructured materials. Roughness tests and microscopic observations showed significant topographical differences, depending on the material and modification process involved. Moreover, in this paper we demonstrate the influence of the substrate and treatments on the wettability. Obtained results confirmed that designed hybrid modification of Ti Grade 2 and TNTZ has significant potential for biomedical applications.
