Abstract: Most natural surfaces and surfaces of engineering interest, e.g., polished or sandblasted surfaces, are self-affine fractal over a wide range of length scales, with the fractal dimension Df=2.15±0.15. We give several examples illustrating this and a simple argument, based on surface fragility, for why the fractal dimension usually is <2.3. A kinetic model of sandblasting is presented, which gives surface topographies and surface roughness power spectra in good agreement with experiments.
