The obtained results of investigations confirm the possibility of formation of solid lubricant coatings (SLC) by using MoS 2 dry powders subjected to the wave vibration impact treatment in a medium of steel beads, which trigger the deformation of the surface layer in the presence of MoS 2 , and the formation of the corresponding coating. Based on the analysis of the results of investigation of the characteristics of vibration treatment in the medium of metallic bodies, we propose a model of the formation of MoS 2 SLC as a result of vibration treatment. The application of SLC in vibration treatment gives a lower friction coefficient and the elevated wear resistance. A physical and mathematical model is proposed for quantitative assessment of the adhesive strength of SLC MoS 2 .
