Abstract

Abstract: Fractal geometry is applied to the characterization of rough surfaces. The variation law of surface topography during running-in period is studied with scale-independent fractal parameters. Based on the basic principle of classical contact mechanics and Rowe’s modified adhesion theory , a fractal prediction model of running-in wear is developed. The effect of surface fractal parameters on wear rate is analyzed with the model. The validity of the model is proved by pin-on-disc experiments.

Key words: Fractal geometry, Model, Running-in, Wear
