The last stage endured on obvious erosion especially the front and the
end of the blade . The erosion caused the appearance some cracks in
this place. These remarks coincided with the theoretic al results ,
which were acquired according to the con
dition of the turbine of
station which showed that the droplet , which collided with the blade
ends, caused high pressure on the surface of the blade and caused
the occurrence of the corrosion . The danger of the erosion
unavoidable due to its relationship with tae station efficiency and the
only to avoid that is the use of the blade made of erosion resistance
ingots .
