It is elucidated that under relatively light loads, irregularities of fractal roughness are initially flow until contact marks, increasing in size, move into elastic state, breaking free of fractality. Upon elastic contact, the friction ratio decreases with increasing load, and in case of fractal model, the friction ratio is on the increase with increasing load, while surfaces with a large value of fractal dimension have a decrease in friction ratio growth.
