Nanoscale surface modification of Ti6Al4V prosthetic material was investigated at 37 degrees C into a physiological liquid named Ringer's solution. The root-mean-square surface roughness evolution of the material as a function of immersion time was evaluated by atomic force microscopy (AFM) and 3D reconstruction of scanning electron microscope images (SEM). The results obtained from both techniques clearly showed a decrease of the root-mean-square surface roughness during the first 6 hours of immersion in the physiological liquid that is followed by a stability of the roughness value at longer durations. Moreover, the study of the roughness parameters extracted from AFM measurements is used to explain the smoothing process occurring at the interface between the prosthetic material and the physiological liquid.
在37摄氏度的名为林格氏液的生理液体中研究了Ti6Al4V假体材料的纳米级表面改性。通过原子力显微镜（AFM）和扫描电子显微镜图像（SEM）的三维重建来评估材料的均方根表面粗糙度随浸泡时间的变化。两种技术获得的结果清楚地表明，在生理液体中浸泡的前6小时内，均方根表面粗糙度降低，随后在更长时间内粗糙度值保持稳定。此外，对从AFM测量中提取的粗糙度参数的研究用于解释假体材料与生理液体之间界面处发生的平滑过程。
