This study aims to examine the wear performance and electrochemical corrosion properties of Ti15Mo alloy produced by mechanical alloying (MA) in simulated body fluid (SBF) environment. Ti15Mo alloy was produced by milling in a mechanical alloying device for 120 min. The alloys produced are examined using SEM, X-ray diffraction, hardness and density measurements. Three different loads, four different sliding distances and 1 m · sec–1 sliding speed were used in the tests performed in SBF environment. Corrosion tests were carried out using potentiodynamic polarization technique, cyclic polarization measurement at 37°C body temperature, in SBF, with a scan interval of ±750 mV and scan rate of 1 mV/sec. Density and hardness measurement results of MA’ed Ti15Mo alloy are 4.93 g/cm3 and 299.5 HV, respectively. As a result of increasing the load applied during the wear tests, the resistance of the samples against wear has decreased and the amount of wear has increased. Corrosion tests showed that the potentiodynamic polarization parameters were 36.969 mA/cm2 for Icorr value and 0.54448 mmpy for corrosion rate. Corrosion tests made in the environment of SBF and at body temperature revealed that there was very little pitting corrosion observed in MA’ed Ti15Mo alloy.

机械合金化法生产的 Ti15Mo 合金在 SBF 环境中的磨损和腐蚀行为研究

本研究旨在研究通过机械合金化 (MA) 制备的 Ti15Mo 合金在模拟体液 (SBF) 环境中的磨损性能和电化学腐蚀性能。Ti15Mo 合金是通过在机械合金化设备中研磨 120 分钟来生产的。使用 SEM、X 射线衍射、硬度和密度测量来检查所生产的合金。在 SBF 环境中进行的测试中使用了三种不同的载荷、四种不同的滑动距离和 1 m·sec-1 的滑动速度。使用动电位极化技术进行腐蚀测试,在 37°C 体温下进行循环极化测量,在 SBF 中,扫描间隔为 ±750 mV,扫描速率为 1 mV/sec。MA'ed Ti15Mo 合金的密度和硬度测量结果分别为 4.93 g/cm3 和 299.5 HV。由于磨损试验期间施加的载荷增加,样品的抗磨损能力降低,磨损量增加。腐蚀试验表明,动电位极化参数的 Icorr 值为 36.969 mA/cm2,腐蚀速率为 0.54448 mmpy。在 SBF 环境和体温下进行的腐蚀试验表明,在 MA'ed Ti15Mo 合金中观察到的点腐蚀非常少。
