The work is devoted to the surface hardening of the covered with thermo and electromechanical hardening, as well as vibro-autistic grinding and jet-dynamic method. An analysis of the impact of strengthening processing on the operational prop-erties of coatings was carried out; The results of experimental studies are presented indicating the methodology of experiment and used equipment and devices.

The article provides information on the designed and implemented processes of combined processing of loaded parts of promising energy installations, described original means of technological equipment, the prospects for expanding their technological capabilities and influence on increasing the production techniques of products are considered.

The effectivities of using the plasma-spraying processes and strengthening of coatings for retailoring of machine details. The results of experiment with coated details and presented.
