A constant normal force is applied by the stylus to the test sample and the scratch track is and considerably reduces the apparent measurement uncertainty, as compared with an unreduced dataset. Measuring setups for both model tribosystems as well as components, e. It is a subject integral to any mechanical system containing moving parts or joints—starting with molecular “machines” (as motor proteins in living cells) (Dudko et al. Using this tribometer, the friction and lubricant performance have been tested, and the repeatability of the system has been studied.
