Original Paper


Lubricant transfer is investigated versus temperature, local pressure change and disk velocity considering lubricant fragmentation for four different types of perfluoropolyether. Lubricant transfer and lubricant fragmentation are found to increase with temperature, local pressure change and velocity of the moving disk. The local pressure change is observed to be the most important parameter accelerating lubricant fragmentation.
