Abstract
Steam turbine fluid directing components are improved in erosive wear resistance by application of either relatively tougher and relatively less hard thermal spray or relatively harder and relatively less tough diffusion alloy surface modification to different portions of the component as a function of the locally greater or locally smaller angle of attack of solid particles on those portions in the use condition of the component.
