Erosion Wear of the Blades of Wet-Steam Turbine Stages: Present State of the Problem and Methods for Solving It

摘要

The results obtained from studies of metal erosion processes are analyzed and generalized, which made it possible to establish the main regularities relating to surface destruction of blade materials under the effect of droplet impingement and determine how the size of liquid droplets and velocity at which they collide with the surface affects the rate of erosion wear for almost all blade materials. Development of efficient technologies for strengthening the surface layer and applying universal durable coatings is the most promising line of activities aimed at making blade materials more resistant to erosion wear.
