The results of evaluating the wear of samples of the model of the same name pair of friction from alloy steel 30KhGSN2A after ion beam treatment and dry friction under conditions of heavy contact are presented. It was shown that in the steady state friction, the wear resistance of steel as a result of implantation of copper ions at an irradiation dose of 1017 ion / cm2 and 5.1017 ion / cm2 increases by 2 and 1.5 times, respectively. The mechanism of the «long-range effect» in ion-doped structural materials under conditions of contact deformation is discussed.

Ion Beam Treatment

Using experimental methods of analysis, the morphology, elemental composition and chemical state of hard alloys of the «TiC-TiNi» system in the initial state and after various types of ion-beam treatment have been investigated. It is found that the effect of a continuous ion beam leads to an increase in the microhardness of the investigated alloys by 10–12 %. When samples are irradiated with a pulsed ion beam, as a result of destruction of surface layers, the microhardness value decreases by 20 %, as a result of which this type of modification is not preferable for alloys of the TiC-TiNi system
