In the case of adhesive and abrasive wear measurements, determining the amount of removed material (ejection volume) plays an important role in understanding the process. The surfaces are often very jagged and the light reflected back shows great intensity differences. The Smart Surface Scanning Technology incorporated into the TopMap systems assures optimal results in such cases.

Wear and tear studies are typical applications for TopMap products. In the adjacent figures, the topography measurements from a brake disk are plotted. The wear abrasion of the brake disks can be seen clearly from the pitting highlighted in green. The results can be used for failure analysis.
