Inert lubricant perfluoropolyether (PFPE) on magnetic hard disk in computer is still prone to catalytic decomposition by Al_2O_3, which is one of the materials in slider. A partial fluorinated hexaphenoxy cyclotriphosphazene 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 also investigated. Contact start-stop (CSS) tester was employed to investigate the reflow effective of X-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.展开更多
