Abstract

The biomedical Ti-13Zr-13Nb bi-phase (α + β) alloy for long-term applications in implantology has recently been developed. The porous oxide nanotubes' (ONTs) layers of various geometries and lengths on the Ti-13Zr-13Nb alloy surface can be produced by anodizing to improve osseointegration. This work was aimed at how anodizing conditions determinatine the micromechanical and biotribological properties of the Ti-13Zr-13Nb alloy. First-generation (1G), second-generation (2G), and third-generation (3G) ONT layers were produced on the Ti-13Zr-13Nb alloy surface by anodizing. The microstructure was characterized using SEM. Micromechanical properties were investigated by the Vickers microhardness test under variable loads. Biotribological properties were examined in Ringer's solution in a reciprocating motion in the ball-on-flat system. The 2D roughness profiles method was used to assess the wear tracks of the tested materials. Wear scars' analysis of the ZrO ball was performed using optical microscopy. It was found that the composition of the electrolyte with the presence of fluoride ions was an essential factor influencing the micromechanical and biotribological properties of the obtained ONT layers. The three-body abrasion wear mechanism was proposed to explain the biotribological wear in Ringer's solution for the Ti-13Zr-13Nb alloy before and after anodizing.

摘要

最近开发了一种用于植入学长期应用的生物医学Ti-13Zr-13Nb双相（α+β）合金。通过阳极氧化可以在Ti-13Zr-13Nb合金表面制备各种几何形状和长度的多孔氧化物纳米管（ONTs）层，以改善骨整合。这项工作旨在研究阳极氧化条件如何决定Ti-13Zr-13Nb合金的微观力学和生物摩擦学性能。通过阳极氧化在Ti-13Zr-13Nb合金表面制备了第一代（1G）、第二代（2G）和第三代（3G）ONT层。使用扫描电子显微镜对微观结构进行了表征。通过在可变载荷下的维氏显微硬度测试研究了微观力学性能。在林格氏溶液中，在球-平面系统中以往复运动的方式研究了生物摩擦学性能。使用二维粗糙度轮廓法评估测试材料的磨损轨迹。使用光学显微镜对ZrO球的磨损疤痕进行了分析。发现含有氟离子的电解液成分是影响所得ONT层微观力学和生物摩擦学性能的关键因素。提出了三体磨料磨损机制来解释阳极氧化前后Ti-13Zr-13Nb合金在林格氏溶液中的生物摩擦学磨损。
