Effect of the additive X-1P on the tribological performance of PFPE lubricant at the head-disk interface

摘要

Perfluoropolyethers (PFPE) are employed as lubricants at the head-disk interface in magnetic recording disk drives to reduce friction and wear. The PFPE lubricant and the carbon overcoat on the disks provide the necessary protection of the underlying magnetic film against wear due to contact sliding. X- 1P, a cyclic phosphazene lubricant, is a non-polymer lubricant being developed for the disk drive industry. This report present studies of the effect of adding X- 1P in PFPE lubricant on the tribochemical wear at the head-disk interface.
