Liu Erjia School of Mechanical and Aerospace Engineering DRNTU::Engineering::Mechanical engineering 101 p. This thesis studies the nanotribological behavior of magnetic rigid disks dip-coated with ultra thin perfluoropolyether (PFPE) Z-Dol 4000 lubricant layers up to 4 nm thick prior to or after exposure to ultraviolet (UV) light irradiation. Bonding lube ratios (BLRs) of 43-91 percent were achieved by varying the UV irradiation time. The nanotribological and mechanical properties of the disks were measured with a nanotribometer under varying loading conditions. The effect of the BLR on the nanotribological behavior of the disks was elucidated. It was found that the lubricated disks after UV treatment performed better compared to the lubricated disks without UV treatment. The experimental results indicated that the BLR of about 50 percent could achieve the best contact-start-stop and flyability performances.
