Abstract:
A method for processing a stator vane of a rotary machine, the stator vane extending circumferentially with respect to an axis A, the stator vane having a platform, and at least one airfoil which extends from the platform and which has a leading edge, comprising: removing the junction of the leading edge with the platform by removing a portion of the leading edge region of the airfoil to form at least one bonding surface on the airfoil facing in a generally axial direction and removing a portion of the platform adjacent the leading edge to form at least one bonding surface on the platform facing in a generally circumferential direction; installing a replacement detail having an airfoil section and a platform section and bonding surfaces which are spaced from the junction and which face the bonding surfaces formed on the stator vane in the installed condition; and bonding) the replacement detail to the stator vane by forming bonds each of which has a bond strength at each bonding surface and wherein the bond strength at the airfoil section is greater than the bond strength at the platform section between circumferentially facing surfaces.
