For bone implants, β‑titanium alloy is promising mainly due to its low modulus of elasticity; the disadvantage may be the insufficient wear-resistant and corrosion-resistant properties. Bulk β-Ti39Nb alloy and magnetron sputtered β-Ti39Nb alloy were surface modified by micro-arc oxidation (MAO) technique in an alkaline solution. The aim was to define in detail the relationships between the chemical composition of the surfaces, their morphology, and the tribological and corrosion properties. The structural properties, phase and chemical composition of the coating, tribological and corrosion properties were studied in detail using SEM, EDX, XRD, XPS and EDX analysis. The particles released during tribological measurements were evaluated using SEM/EDX particle analysis followed by statistical treatment of the particle parameters (material, size, area) using multiple factor analysis and principal component analysis. The results show that increased wear resistance was achieved for both magnetron-sputtered layers and bulk materials. The friction coefficient for the MAO-Al₂O₃ friction pair samples ranged from 0.5 to 0.6 in phosphate-buffered solution. For powder metallurgy-prepared bulk β-Ti39Nb, MAO represents an effective tool to reduce the high friction coefficient from 1.0 to 1.1 to values of 0.4–0.5. The results of the particle analysis confirm that with increasing MAO process time, there is an increase in the number of released particles with increased Si content, which correlates well with the results of tribological tests. The evaluated tribological parameters wear rate, track width, and the chemical elements Si and Ti have a significant weak positive correlation, confirming that the presence of these elements in MAO coatings affects the resulting tribological parameters. Multivariate analysis revealed the greatest correlation of the resulting particle composition with the tribological attributes and original material and, to a lesser extent, with the process time.

对于骨植入物，β钛合金主要由于其低弹性模量而具有广阔的前景；缺点是耐磨、耐腐蚀性能不够。采用微弧氧化（MAO）技术在碱性溶液中对块状β-Ti39Nb合金和磁控溅射β-Ti39Nb合金进行表面改性。目的是详细定义表面化学成分、形态以及摩擦学和腐蚀特性之间的关系。利用SEM、EDX、XRD、XPS和EDX分析详细研究了涂层的结构性能、物相和化学成分、摩擦学和腐蚀性能。使用 SEM/EDX 颗粒分析评估摩擦学测量期间释放的颗粒，然后使用多因素分析和主成分分析对颗粒参数（材料、尺寸、面积）进行统计处理。结果表明，磁控溅射层和块体材料的耐磨性均得到提高。_{MAO-Al 2} O ₃摩擦副样品在磷酸盐缓冲溶液中的摩擦系数范围为0.5至0.6。对于粉末冶金制备的块状 β-Ti39Nb，MAO 是将高摩擦系数从 1.0 降低到 1.1 至 0.4-0.5 的有效工具。颗粒分析结果证实，随着 MAO 处理时间的增加，释放颗粒的数量随着 Si 含量的增加而增加，这与摩擦学测试的结果密切相关。评估的摩擦学参数磨损率、轮距宽度与化学元素Si和Ti具有显着的弱正相关性，证实MAO涂层中这些元素的存在会影响所得的摩擦学参数。多变量分析揭示了所得颗粒成分与摩擦学属性和原始材料的最大相关性，以及在较小程度上与加工时间的相关性。
