Comparison of a 2-Dimensional Wear Scar Measurement and a 3-Dimensional Profilometer Measurement of the Same Wear Scar in a Point Contact

In a tribological experiment, one relies on the ability to measure accurately the wear scar in the contact. Usually, in a point contact, the wear scar diameter (WSD) is measured, and measurements of this kind may be compared for several different oils, for example. This type of experiment might be c...
