For this study, researchers used MountainsMap® to compare the load bearing
characteristics of snakeskin from two different species with that of industrially honed cylinder liners.
Results showed several similarities between the two types of surface, opening up new possibilities for integrating features from the
bio-surface studied into engineered surfaces.
WLI interferograms of several regions of the surfaces studied (snakeskin & cylinder liner).
MountainsMap® tools used
Calculation of ISO 25178 surface texture parameters allowing quantitative comparison of surface features:
- Average roughness (Sa)
- Root mean square roughness (Sq)
- Surface kurtosis (Sku)
- Surface skewness (Ssk)
Abbott-Firestone Load curve allowing measurement of load-bearing characteristics of surfaces
Calculation of bearing ratio parameters characterizing the functional aspect of the surfaces studied:
- Kernel roughness depth (Rk)
- Peak roughness height (Rpk)
- Valley roughness height (Rvk)
