microtest mt pin-on-disk tribometer
DESCRIPTION
The pin-on-disk tribometer serves for the investigation and simulation of friction and wear processes under sliding conditions. It can be operated for solid friction without lubrication and for boundary lubrication with liquid lubricants. Thus both material and lubricant tests can be executed.TRANSCRIPT
