Surface Wear Subtraction Using 3D Profilometry
In this application the Nanovea ST400 Profilometer is used to measure the surface wear of a golf ball before and after wearing of the surface with sandpaper. The two profile measurements were then combined through software surface subtraction to analyze wear volume loss. This feature is ideal for applications such as but not limited to: wear, corrosion and lubrication failure.

Wood Coatings Wear Resistance using Tribometer
In this application, the Nanovea Tribometer is used to measure the wear resistance of a coated wood pencil. The linear wear test (ASTM G133) was used with a 3mm stainless steal ball tip; many other tips could have been used. The 1st test was performed for 4 hours and then a 2nd test was performed for 1.5 hours. After wear testing the 3D Profilometer integrated on the Tribometer was used to profile the wear track.
