摘要：
It is shown that in the course of vibration-wave treatment a solid lubricant coating is formed on steel from molybdenum-disulfide powder. The morphological features of the coating are investigated. Using electron probe microanalysis and infrared spectroscopy, it is found that the chemical composition of the coating both during vibration processing and after friction tests remains unchanged. A theoretical estimation is performed for the energy of adhesion between the MoS2 coating and the protected steel surface using a model that takes into account the pairwise and triple potential interactions between the particles of the contacting materials. It is shown that the adhesive interaction between MoS2 particles and steel is significantly more intense than the adhesive interaction in the system of MoS2-MoS2 particles. The energy of adhesive interaction is calculated for the MoS2-MoS2 (-0.04 x 10(10) J/m(3)), MoS2-Fe pairs (-0.54 x 10(10) J/m(3)). Theoretical calculations confirm the results of experiments on studying the adhesive properties of the MoS2 coating.
