摘要
Nonreactive perfluoropolyether lubricants were processed by ultraviolet (UV) radiation to make them chemically bonded to thin film magnetic disks. The tribological performance of these disks was then investigated. Disks with a range of 30-50 angstrom thick perfluoropolyether lubricant, were treated by using the different sources of UV radiations in air, argon, and nitrogen atmospheres. By changing the power density from 40 mW/cm2 to 50 W/cm2 and UV wavelength 185 to 365 nm, in either dry nitrogen or argon gas, a maximum of 38 angstrom of lubricant was chemically bonded to the thin film disks. Stiction and friction forces during 1 rpm testing were dramatically decreased with the increase in UV exposure time. Contact-start-stop test performance of disks with approximately 15%-30% of chemically bonded lubricant was also significantly enhanced. An optimum amount of chemically bonded lubricant provides excellent tribological performance for thin film disks.
