Inertlubricant perfluoropolyether (PFPE) on magnetic hard disk in computer is still prone to catalyticdecomposition by Al₂O₃, which is one of the materials in slider. A partial fluorinated hexaphenoxycyclotriphosphazene chemical, X-1 P, was analyzed to research on its function to reduce the cata-lytic decomposition of lubricant. The surface free energy of X-1 P coated on head surface was alsoinvestigated. Contact start-stop (CSS) tester was employed to investigate the reflow effective ofX-1 P on lubricant PFPE. Results indicate that thermal stability and reflow of lubricant will be im-proved in the presence of X-1 P on the slider. 关 键 词：head/disk INTERFACE surface COATING X-1P
