Scratch Testing

The Femto-Indenter can be upgraded with a Scratch Testing Module to enable nano-scratch and nano-wear testing, as well as SPM imaging. The diamond tip of a 2-Axis Microforce Sensing Probe is pushed across the sample surface while applying a ramping or constant normal load at a given speed. Scratch testing yields quantitative insights into tribological properties and failure mechanisms at the nanoscale, including thin film adhesion, friction coefficient and scratch or wear resistance of materials. Furthermore, high-resolution SPM imaging can be used for topography imaging before and after scratch, wear or nanoindentation testing. It provides direct visualization of pre-test surface roughness and post-test surface deformation or damage.
