Corrosion resistance of reinforced layers of 15Х11МФ steel steam turbine blades

Corrosion tests of blade samples were carried out, the leading edges of which are reinforced in three ways: by reinforcing with high-frequency currents, electrospark alloying with T15K6 alloy, and electrospark alloying with 15Х1МФ-Ш steel. According to the results of the tests, the layer reinforced by quenching with high-frequency currents has the lowest rate of corrosion, and the layer reinforced by electrospark alloying with T15K6 hard alloy has the highest rate. The corrosion rate of a layer reinforced with electrospark alloying with 15Х11МФ steel is 2.1 less than that of a layer reinforced with T15K6 alloy.
