The reliability of the vane apparatus of steam turbines largely determines the operation of the turbine as a whole. The results of scientific research indicate that the surface operation of the blades in the wet-steam flow is caused by a combination of corrosion and drip erosion. The presence of chemical elements and compounds in the working fluid intensifies the process of blade wear. The pH value of the working environment, which can fluctuate significantly during operation, has a significant effect on the wear characteristics. The influence of methods of strengthening the leading edges of steam turbine blades made of steel is analyzed 15H11MF on corrosion resistance. Corrosion tests of blade samples were carried out, the inlet edges of which were strengthened in three ways: high current amplification, electrospark alloying with T15K6 alloy, electrospark alloying with steel 15H11MF. According to the results of the tests, the layer strengthened by hardening by high-frequency currents has the lowest corrosion rate, the layer strengthened by electrospark alloying with T15K6 hard alloy has the highest. The corrosion rate of the layer reinforced by electrospark alloying of steel 15H11MF is 2.1 less than that of the layer reinforced with T15K6 alloy.

Currently, the use of new methods of surface strengthening has become relevant to improve the working tool. These methods include detonation sputtering. The purpose of this work was to scientifically substantiate and experimentally confirm the effectiveness of strengthening critical parts of a hydraulic hammer by detonation sputtering. As a result of the study, the effect of detonation sputtering on the wear resistance and mechanical properties of the hydraulic hammer working tool was established, and structural changes in the material during its operation were analyzed. The results of testing parts strengthened with detonation sputtering show that an increase in wear resistance by 1.8 times is achieved compared to the initial state.
