Abstract

A problem of providing erosive resistance of movable blades of the last stage of power steam turbines when applying anti-erosive protective coat using method of atomic-ionic dispersion of materials has been considered. The problem can be solved with the help of the worked out universal mathematical model of drop impact erosion. The choice of parameters of the protective coat for the movable blades of the last stage has been grounded. Results of the comparison of the received theoretical and experimental data have been shown
