| Abstract: | By fractal analysis, the investigation were made on dry sliding surface morphologies of phosphorous compacted iron. The results show that fractal analysis technology is suitable for describing the characteristics of dry sliding surface, and that the fractal dimension is an appropriate single value parameter for reflecting surface roughness. For phosphorous compacted iron, an internal relation exists between the fractal dimension and tribological properties of the surface, and the effect of different dry sliding condition and fractal dimensions on tribological properties shows a very complicated relationship. |
