ABSTRACT
Research and academic communities are interested in the latest devices for surface analysis and often papers are published in which the authors applied several surface characterization techniques to worn surfaces without any clear reason or vision for doing so. There are numerous characterization techniques available for worn surfaces. The instrument can also be used to measure and map mechanical properties and behavior of solid material surfaces down to the nanoscale. When studying objects with microscopes, it is often useful to think about the scale of observation relative to the scale of size of various things. Optical microscopy is perhaps the oldest, easiest to use and most commonly used technique for worn surface examination. The stylus moves along a solid surface, rising over the peaks and descending into the valleys as it moves. The lineal roughness parameters and line surface profile can also be determined at a specific location from the optical profilometry measurements.
