Abstract: Traditional statistical parameters of rough surface are dependent of sampling interval and resolution of the instrument.Fractal parameters can be used to characterize surface profile because of their scale independent and self affinity.Taking rigid disk surface as an example,fractal parameters are obtained by means of power spectrum and structure function,providing a proper geometric model for further contact analysis.

Key words: fractal geometry, surface topography, contact, disk
