Abstract

CoCrPt-C nanogranular thin films, with high coercivity after annealing treatment, were prepared in this work. To achieve the expected lubricant-free disks, nano-wear tests and frictional measurements were carried out on these unlubricated samples using a diamond-tipped scanning probe microscope and a lateral force microscope respectively. We observed that the structure of carbon in the films varied with the content of carbon and annealing treatment. The friction and wear are influenced by the thickness of top-layer carbon and interlayer carbon. Friction is reduced after annealing treatment and wear resistance increases with a decrease of the Raman spectra intensity ratio of D-band to G-band.
