[19p-PA1-1] Evaluation of Friction and Abrasion by Power Spectral Density and Slope Histogram
Keywords:morphology
Surface configurations and dynamical friction coefficients of various metals were measured and evaluated by surface histogram and power spectral density (PSD). Surface histogram was fitted in a standard deviation. The standard deviations could be used as an index of surface roughness. PSD’s were fitted in a function of f -n type. Surface roughness measurements by AFM as another equipment would be reported.
