Contact.engineering—Create, analyze and publish digital surface twins from topography measurements across many scales

Abstract: The optimization of surface finish to improve performance, such as adhesion, friction, wear, fatigue life, or interfacial transport, occurs largely through trial and error, despite significant advancements in the relevant science. There are three central challenges that account for this disconnect: (1) the challenge of integration of many different types of measurement for the same surface to capture the multi-scale nature of roughness; (2) the technical complexity of implementing spectral analysis methods, an… Show more

“…However, because many conventional measurements of surface topography do not provide scale-dependent information, it is not clear at this moment which treatments should be applied to modify the roughness at a specific scale. The authors believe further investigation in this vein is warranted, along the lines of refs and . We believe this is the missing piece in the rational design of bioactive surfaces.…”

“…The PSD is shown in Figure 3 , with the frequency-space wavevector on the bottom x -axis and the real-space lateral size scale (wavelength) on the top x -axis. A reliability analysis is performed for each surface characterization technique 30 to assess the impact of resolution limits and tip-radius artifacts; then, the unreliable data was removed. The PSD was computed for each individual measurement, and these were combined into a single surface descriptor by taking the average at each wavevector.…”

“…The details of the calculation of the PSD can vary across different software implementations. Here, we used the open-source analysis code from the freely-available web application https://contact.engineering, which is fully documented in [24]. Furthermore a power spectral density can be calculated from 2D (line-scan) or 3D (areascan) measurements of topography; at all points in this paper, PSDs were computed using the line-scan approach to ensure an apples-to-apples comparison across all techniques.…”
