摘要：
An algorithm has been developed for the analysis of asperities of various types of machined surfaces, in order to characterize wear processes in the course of dry friction. Wear experiments and surface roughness measurements were performed to study the microtopographies of worn surfaces. Investigations extended to wear in the case of the non-lubricated ceramic-steel clutch and lubricated camshaft and bushing. A statistical analysis of asperities and scratches was completed with distribution curves to display the results. The peak angle, the rate of the major and minor axis and orientation were analyzed to characterize the shape of asperities and the overall characteristics of the surface.
