An acoustic model of the boundary friction process has been elaborated where the transformation of surface Rayleigh waves into space ones is considered under account for damping on dislocations. A relationship similar to the overturned resonance curve has been found between the specific friction force and the Rayleigh waves frequency. The specific friction force has been shown to be in proportion to the wavelength of the surface microrelief and in inverse proportion to square of the surface dislocation density.
