Abstract The melting of ultrathin lubricant film by friction between atomically flat surfaces is studied. In the case of a second-order transition the spatial distributions of the elastic shear stress and stain, and the temperature are described on the basis of Ginzburg-Landau equation. The additive noises of above quantities are introduced for building a phase diagrams with the domains of sliding, stick-slip, and dry friction. It is shown that increase of the strain noise intensity causes the lubricant film melting even at low temperatures of the friction surfaces. Taking into account the deformational defect of the shear modulus the analogical phase diagrams are obtained in the case of a first-order transition.
