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

activation of components
