Methods & Expertise for Research Infrastructure
prior to wear measurement, the relevant components are partially activated with radioactive tracer isotopes; the wear particles produced in the friction zone during operation are transported through the integrated lubricant circuit to a gamma radiation detector; the activity of the tracer-isotopes in the wear particles which is measured by the detector can be directly converted into wear measurements at any point during operation; with this method even the lowest wear rates in the range of nm/h can be measured, a condition monitoring of the functionality of stressed system components is achieved, a service life prediction of critical components is derived, the wear resistance of materials and coatings is assessed and the wear protection effect of lubricants is evaluated.
