Qualifying Surface and Device Performance Through Roughness Quantification

This interactive webinar will focus on how engineers can accurately measure micro-roughness of surfaces using non-contact optical profilometry and importantly use specific analyses to rank materials and assess their ultimate performance.

We will explain how data analysis using the 3D international standard ISO 25178 norm can be exploited to rank surface properties and explain wear processes. The use of mean roughness and other areal roughness parameters to differentiate surfaces and quantify their efficiency for intended applications will be described including aesthetic appearance and corrosion resistance. Case studies from the automotive, sensors, optics and medical industries will be presented.

Who Should Attend?

The webinar will be beneficial for any scientist or engineer working in R&D, Process and Quality Control interested in characterizing the metrology, tribology and surface related performance of materials and devices.
