This paper presents the possibilities of applying atomic force microscopy (AFM) techniques to the study of the wear of prosthetic biomaterials. In the conducted research, a zirconium oxide sphere was used as a test piece for mashing, which was moved over the surface of selected biomaterials: polyether ether ketone (PEEK) and dental gold alloy (Degulor M). The process was carried out with constant load force in an artificial saliva environment (Mucinox). An atomic force microscope with an active piezoresistive lever was used to measure wear at the nanoscale. The advantage of the proposed technology is the high resolution of observation (less than 0.5 nm) in the three-dimensional (3D) measurements in a working area of 50 × 50 × 10 µm. The results of nano wear measurements in two measurement setups are presented: zirconia sphere (Degulor M and zirconia sphere) and PEEK were examined. The wear analysis was carried out using appropriate software. Achieved results present a tendency coincident with the macroscopic parameters of materials.
本文介绍了应用原子力显微镜（AFM）技术研究生物医用材料磨损情况的可能性。在进行的研究中，使用氧化锆球体作为研磨试件，使其在选定的生物材料表面移动，这些生物材料包括聚醚醚酮（PEEK）和牙科金合金（Degulor M）。该过程在人工唾液环境（Mucinox）中以恒定负载力进行。使用带有有源压阻式杠杆的原子力显微镜在纳米尺度上测量磨损。所提出技术的优点是在50×50×10 µm的工作区域内进行三维（3D）测量时具有高分辨率观测（小于0.5 nm）。给出了两种测量设置下的纳米磨损测量结果：对氧化锆球体（Degulor M和氧化锆球体）以及PEEK进行了检测。使用适当的软件进行磨损分析。获得的结果呈现出与材料宏观参数相符的趋势。
