The results of theoretical researches of process of the thermal effects of supersonic gas flow on the hemispherical fairings of optical ceramics IR-devices homing and tracking, determining the location on the surface plots the maximum external thermo-influences, where the destruction of the fairings, which leads to failure of the device. The results of experimental researches of properties of surface layers of these areas by the finish of electron beam processing, which leads to increased durability of the fairings to the external thermal and mechanical stresses and decrease in the amount of damage and improve efficiency of the devices during their operation.
