This paper presents the tribological properties of silicon and oxygen incorporated diamond-like carbon coatings tested in simulated body fluid and bovine serum albumin environments. The tests were performed using a ball-on-disc tribometer with an AISI316L steel counterbody. The wear tracks and wear scars were analyzed using optical microscopy and a nanoindenter. The interaction between the coating and the working environment was analyzed by Fourier transform infrared spectroscopy, whereas changes in the chemical structure before and after the tribological tests were compared with the use of Raman spectroscopy. Our study showed that the tribological parameters are governed by the presence of oxygen rather than the changing concentration of silicon. Both of the spectroscopy results confirm this statement, indicating that coatings with low concentrations of silicon and oxygen appear to be better candidates for biological applications in terms of wear resistance.
本文介绍了在模拟体液和牛血清白蛋白环境中测试的含硅和氧的类金刚石碳涂层的摩擦学性能。使用带有AISI316L钢对磨体的球盘摩擦磨损试验机进行测试。使用光学显微镜和纳米压痕仪分析磨损轨迹和磨损疤痕。通过傅里叶变换红外光谱分析涂层与工作环境之间的相互作用,而通过拉曼光谱比较摩擦学测试前后的化学结构变化。我们的研究表明,摩擦学参数受氧的存在而非硅浓度变化的支配。两种光谱分析结果均证实了这一说法,表明就耐磨性而言,低硅和低氧浓度的涂层似乎是生物应用的更佳候选材料。
