Based on 3-D surface morphology measurements of C.G. irons, the fractal analyses were made on relationship between dry sliding surface morphology and the fractal dimension. It is revealed that the values of fractal dimensions (Df) of sliding surfaces are in the range between 1-2, which are closely related to the surface morphologies. With the increase in depths of grooves or pits, the Df values increase. At the same lime, the increases in densities of the grooves also cause the Df values to increase. At last, relationship among Df and friction coefficient as well as wear rate is discussed.
