摘要：

For development of rational methods of friction hardening of parts subjected to chemicothermal treatment (guideways, lower blanking dies, drill bits, internal combustion engine crankshafts, etc. ), the distributions of temperature and stresses occurring in their surface layers is analyzed. For this purpose the problem is considered in which a part is simulated by a half-space with a coating, the physicomechanical properties of which, with the exception of the Poisson's ratios, differ substantially. It is established that an increase in the coefficient of heat transfer from the surface beyond the limits of the heating band leads to a decrease in the maximum values of temperature and temperature stresses at any constant depth of the half-space.
