提出了一种检测和定量转印膜的新方法。它是基于在摩擦学实验过程中连续记录的摄影图像的分割和数值分析。由此，提取磨损痕迹亮度的变化并用作转印膜形成的定量测量。与现有的方法相比，新方法是横向广泛的，原位适用的，时间分辨的，定量的，无限的可持续性和实际上不受限制的材料选择。详细介绍了该方法在ASTM G137环块试验中的应用，以及数据提取和结果绘图的过程。特别要注意磨损痕迹抛光的问题，如果不加以考虑，可能会导致误导性的数据。
A novel method for the detection and quantification of transfer films is presented. It is based on the segmentation and numeric analysis of photographic images that are recorded continuously during a tribological experiment. From these, the change of the wear track luminance is extracted and used as quantitative measure for transfer film formation. In contrast to existing methods, the novel method is laterally extensive, in-situ applicable, time resolved, quantitative, infinitely sustainable and practically unrestricted concerning material selection. Its implementation in an ASTM G137 block-on-ring test and the procedure for data extraction and result plotting are reported in detail. Special attention is paid to the issue of wear track polishing, which – when unaccounted for – can result in misleading data.
