Abstract
The technologies of strengthening articles of the steam-turbine flow path (working blades, disks, and shafts) that are developed and introduced into practice are considered. These technologies are aimed at increasing reliability and wear resistance. Information is presented on fretting technology for disks and attachment roots of working blades using rolling-out methods, pneumatic shot-blasting strengthening, and diamond smoothing, as well as regarding protective-coating deposition and electric-spark alloying technologies for working parts of the blades. The results from studies conducted at the stage of mastering these technologies and their introduction into practice are given.
