Abstract
Degradation products of perfluoropolyether lubricants are observed dur ing friction tests on thin film magnetic recording disks using a mass spectrometer. The friction tests are conducted in high vacuum using th in film read-write heads as sliders. Fomblin Z-dol and Krytox 143AX ar e used as lubricant. Observed removal rates are significant compared w ith the lubricant film thickness used. The data suggest that the degra dation reaction is activated by low energy electrons produced at the t ribological interface.
