Abstract
A steam turbine blade is provided having a trailing edge portion formed from an erosion resistant material deposited on the blade airfoil by a friction surfacing method. According to the method, a rotating consumable rod of erosion resistant material is placed in contact under axial load against a bonding surface formed on the airfoil, thereby causing a portion of the rod adjacent the bonding surface to be plasticized. The rod then traverses the surface linearly leaving in its wake a layer of erosion resistant material bonded to the airfoil by a high quality metallurgical bond. The layer is then ground to form the smooth contour desired for the trailing edge.
