Surface Metrology

Our high-precision metrology equipment enables us to quantify the finish and form of surfaces

Talk to us about surface metrology

Using metrology we can measure the roughness, texture, shape and form of a sample’s surface.

We typically use this technique to provide extra information for friction, wear and erosion testing projects, and to help identify failure mechanisms. For example, surface metrology enables us to:

  • measure the roughness of a surface before and after testing
  • accurately measure volume loss after a wear test, or
  • confirm whether our lab-simulated wear matches in-service wear
  • map rough textures such as fracture surfaces to help determine why a component has failed.

From using a portable profilometer to measure the surface of railway tracks in situ, to helping microbiologists understand how the roughness of handrails affects the spread of antibiotic-resistant superbugs, it’s a technique we use across many types of test and investigation.

  • Metrology is a powerful technique for getting metrics about a surface. It complements other investigations such as wear testing or can give us clues about why something has failed.

Our surface metrology service

With both contact and non-contact systems at our fingertips we can offer flexible solutions. We will select the most appropriate metrology tools depending on the size and location of your sample material and the type of data required.

  • Contact systems include a hand-held Surtronic S125 and a semi-portable Form Talysurf Intra Touch.
  • We have two non-contact (optical) systems for high-precision 3D surface mapping: the PROSCAN 2100 profilometer and the Alicona InfiniteFocus 3D mapping system.
  • Where it is not practical to test a surface in situ, we can use a quick-setting compound to replicate a surface to 0.1 of a micron, and take the replica to the lab for testing.

Data analysis

We will analyse the data, usually in the context of a suite of test results and measurements. Our expert team will provide a full report and will be happy to discuss the findings with you.
