154 coefficient of thermal conductivity falls with growth of rigidity and hardness of material of bodies; 2) values of temperature difference of contact bodies grow with growths of thermal conductivity of lower body, rigidity and hardness of frictional couples; and values of temperature difference of contact bodies fall with growth of thermal conductivity of upper body; 3) change of nominal pressure between bodies on the contact area has a minor influence on the values of difference of heat fluxes in the bodies; 4) values of heat fluxes of contact bodies grow with growth of thermal conductivity of upper body, and values of temperature difference of contact bodies falls with growth of thermal conductivity of upper body, and values of heat fluxes of contact bodies fall with growth of thermal conductivity of lower body; 5) change of rigidity and hardness of material of bodies has a minor influence on the values of difference of heat fluxes in this bodies. Note, that values of coefficient of thermal conductivity obtained in one- dimensional contact problems, may be used in the modelling of two-dimensional contact problems [4, p. 86]. Fig. 3. Scheme of the tribological contact In this case friction heating of system punch-elastic half plane when sliding along creative line is considered (Fig. 3). Model of so-called ―third body‖, i.e., thin near-surface and intermediate layers, the physical and mechanical properties of which
