RIC3 - Radio Isotope Concentration methode
Use of device
continuous wear measurement in the range of nm/h by means of activated components in real and model systems
Basic function
the components of a tribological system are activated in a cyclotron; the wear particles produced by the tribological process are transported to a detector via a lubricant circuit attached to the tribosystem; the amount of wear is determined from the measured activity throughout the period of operation
Result of analysis
wear depth and wear volume during operation
Goal of analysis
prediction of lifetime, wear resistance of components; wear protection due to lubricant properties
Technical specification
Sample requirement
