| Summary: | Title from the title-page. An analysis of erosion mechanisms of the solid surface under the treatment with submicrosecond ion beams in the power range W = 106…5⋅109 W/cm2 is made on a base of our calculations and scientific literature data. Sputtering and evaporation have been examined. A flow of atoms leaving the surface is divided on two partial components. One of them is caused by sputtering and another by evaporation. Proportion of these components is determined by surface thermodynamic state which depends on power and duration of radiation. It's possible to fix three ranges of the beam power density in an exhibition of erosion mechanisms. Below W ~ (1…5)⋅106 W/cm2 the atomic flow from the surface produced by sputtering is dominate. An erosion ratio doesn't exceed some tens of units. At W ~ (0.5…1)⋅108 W/cm2 and above the erosion is connected with intensive evaporation. The erosion ratio is in range 104…105 atoms/ion. The range W ~ 5⋅106…5⋅107 W/cm2 is studied insufficiently. We suppose that the contributions of sputtering and evaporation into the atomic flow from the surface may be commensurable here. Under these conditions the total erosion ratio is less on orders then in the case of intensive evaporation around an temperature of boiling point.
