Abstract: During the operation of turbines the surfaces of the blades are roughened by corrosion, erosion and deposits. The generated roughness is usually greater than that produced by manufacture. The ...

Abstract: The costs of the manufacturing of turbine blades are very dependent on the manufacturing tolerances and the quality of the surface. A good performance of a turbine needs a certain smoothness ...

Abstract: During operation the blading of turbines undergoes certain changes. Corrosion, erosion, and contamination cause deterioration of the surface quality and blade profile changes. As a result, the ...
