Abstract: It has been established that, with the optimum parameters of the electron beam (thermal pressure density, speed) in the result of the surface flowing of optical parts, there is an improvement in the physical and mechanical properties of their surface layers: the purity and smoothness of the surface increases; microfirmity is increasing; hardened layers with compressive stresses appear; the changes in the structure of the surface layers and their homogenization occur; flint-oxygenic grid becomes similar to the quartz glass. This results into the increase of the resistance of the elements to the external thermal and mechanical effects and ultimately improves the reliability of the appliances when they are operated under extreme conditions (elevated heating temperatures, supersonic airflow, axisymmetric rotation, etc.)
