Abstract
The friction and wear behavior of diamond-like carbon (DLC) overcoated sliders is investigated as a function of DLC overcoat thickness using contact-start-stop and constant speed drag tests. The dependence of t he Raman signal on DLC film thickness is studied. Raman spectra obtain ed from different locations on the air bearing surface are analyzed be fore and after wear testing to study wear of the DLC overcoat. The dep endence of D and G band areas on DLC film thickness is investigated an d the use of Raman spectroscopy for auxiliary measurement of carbon ov ercoat thickness is discussed.
