Abstract (en)
[origin: EP0492323A2] The invention relates to a method for the surface treatment of parts by means of shot peening. An MCrAlY layer is first deposited on the surface of the part as an oxidation and hot-gas corrosion layer. Then the layer surface is shot-peened using a jet of particles having a jet intensity of not more than 0.15 mm Almen A, a coverage of not less than 400% and a mean jet particle diameter of not more than 0.5 mm to smooth and compact the surface. The method is particularly suitable for the surfaces of high-pressure turbine blades having a low radius of curvature at the leading and trailing edge.
