This system, also called XRF (X-Ray Induced Fluorescence) is used to measure the thickness of coatings. Once calibrated, it could be used to not only measure the thickness of flat substrates but also focus on the very cutting iedge of any cutting tool including drills and endmills.
Like the Fischersciope, this system is also used to measure the thickness of coatings. In addition, it reveals the stack of individual coatings layered to comprise the overall coating.
A tribometer is an instrument used to measure the coefficient of friction between to surfaces in contact and set to move against each other. This instrument is used for coatings designed to reduce friction on substrates such as bearings.
