Abstract
Lubricant loss, degradation and mobility of perfluorinated poly-ether (PFPE) on carbon coated disks were investigated by observing friction during sliding contact while controlling temperature and humidity. Lubricant loss from asperity contacts and its replenishment from adjacent areas were investigated for Al2O3-TiC and Mn-Zn ferrite sliders at various sliding velocities by continuous and oscillating rotation of the disk.
