Engine tribology

Components in engines have ultra small wear speeds in the range of a few nanometers per hour under optimal break-in. Radio nuclide technology is used to analyze such systems, capturing this small wear rate in real time. Thus, it is possible to use the main leverage of tribological optimization - dynamics of break-in, additive chemistry, and energy controlled finishing. Besides a drastic reduction in friction and wear, the system is also stabilised, with a simultaneous reduction in sensitivity.
