The electrospark covering of metal surfaces fall under the category of coverings with regulated step of mass carrying. In a considered case the particles of mass carry vary from fine balls up to oval-conical formations on a surface of the covered metal sample. More often a electrospark covering make from a heterogeneous material in relation to a material of a base of the sample. The one-act power impulse covers action the area of the discharge. In a superficial layer of the processable sample in areas of heterojunctions are formed subzones of mutual diffusion and a zone of thermal influence accordingly. In separate cases of interaction of a base of a material of the sample and transferable metal, an alloy, a composite, leads to formation of intermetallic phases how a result of "dotted" electrometallurgy on a surface of the sample. Mechanical operational trials sometimes lead to crumbling of rough of electrospark covering. The mass carrying at the electrospark discharge, local diffusion, a local warming up and cooling on a surface of the processable sample is accompanied by sudden jumps of expansions and compression, which shape superficial and volumetric elastic waves. In turn, they influence structure of a material on deformation and on defective states in a superficial layer of a base of the sample. Similar function carry out at process offriction of periodical move of pressure on surface of sample and friction, causing the moments of forces on elements of a covering and a wave of a local warming up. As a result, superficial states in a covering, in the field of heterojunctions and their nearest environment are in addition in the periodic excited state with the residual consequences changing a substructure of an initial material. The electrospark covering on lapped surface from unheat steel 45 was manufactured at the second operation of processing on “Impuls – 02” installation. As the anode for electrospark carrying graphite, spring steel 65G, chrome, molybdenum, bronze were used. For comparison the samples from initial unheat and heat of steel 45 were investigated. Prevalence of oval-conical elements in a covering with wide base in the field of contact to a base of the sample has made them stable to tribological trials. It has allowed to transfer on discrete areas of a surface of worked samples steady properties of material applied. It was studied a trance-influence through elements of a electrospark covering of disturbance waves in the form of sample of pressure cyclically displacement on a surface and corresponding frictional forces on thin structure of a base of the sample from unheat steel 45 ( ν = 1,33Гц, during 20hours; scope of movings L = 45mm; pressure upon elements of a covering from P1 = 144,4 MPa ÷ 188,9 MPa up to P2 = 48,2 MPa ÷ 63,0 MPa). Changes of structural characteristics of a base of the sample after formation of covering and its trial for a attrition were investigated for specified above harsh conditions of wear of rubbing pair. The functional part of a surface of the investigated samples represents rectilinear streak by breadth 3mm. As a counterbody the plate by thickness 3mm from heat steel 45 was used. Influence of friction on the structures of a base of samples and on the coverings were examined in pure vaseline oil. Diffraction pattems were received at FeK α-radiation.Preparatory polishing of a surface of initial samples from unheat steel 45 was made. From different samples and sites on their surface was got such scatter for the sizes of grains D-5,6Å , 26,2Å, 34,5Å, 55,8Å, of relative microdeformation ε є [1,8·10-3;1,54·10-1 ], of density of dislocation ρ є [3,14·10-10 disl/cm2; 2,79 10-14 disl/cm2 ]. Marked variations of parameters testify, in particular, about significant accumulative-relaxational processes in a superficial layer of a material at its polishing. On sites of different velocities of a motion loaded (see above) counterbodies, value of D grow up to 61,9Å , 375,3Å , 1278,4Å accordingly. The differentiation of parameters of a substructure on a line of friction is detected along diffraction pattems from different parts of the sample. In consideration of physics of process of friction, is possible the realization of some wave of modulation of statistics of distribution of substructure parameters in superficial layer of material along line of friction. In turn, it supposes some local and zone variations of the physicochemical characteristics of a material and their displacement along a surface of the linear sample. Some statistical parameters spread of a substructure of a superficial layer from the sample to the sample and along the linear sample with polycrystalline structure is the usual phenomenon. However, it is possible to note a series of the expressed tendencies connected with changes on a surface of a material of a base of the sample both as a result of formation of a covering, and in consequence of tribological trials. Carrying by electrospark method of carbon, of spring steel 65G, of chrome, of bronze on a surface of steel 45 and subsequent tribological trials of such surfaces lead to growth of the relative microdeformation and density of dislocations in a superficial layer of base of samples. It is necessary to note, that oneself a process of carrying chrome on steel 45 considerably decrease in it these parameters.
