Abstract
Possible mechanisms of the known effect of decreasing friction to anomalously low values in laminar structures of dichalcogenides of transition metals during the irradiation by an ionizing flux are considered. With allowance for the current understanding of complex self-consistent processes of charging dielectrics by particle fluxes, it is shown that the Coulomb repulsion of subsurface layers is the most probable cause of decreasing friction. This effect lasts until an uncompensated surface charge is retained; as the charge drains, it gets weaker.
