Abstract: An upstream rail of a turbine engine turbine casing, which includes a casing body extending along a longitudinal axis, includes a base including a radial face, extending substantially radially from the casing body, a plate including an upper face, extending substantially along the longitudinal axis, a connection portion between the base and the plate, including a concave face connecting the radial and upper faces, the concave and radial faces extending on either side of an edge. The upstream rail is repaired through a method including covering a surface with a solder, the surface including the upper and concave faces such that the solder extends until the edge, and machining the covered surface, in a single action, in a direction toward the radial face, so as to reshape the surface, wherein the machining of the covered surface is performed on a portion of the radial face.

Abstract: A vane (54) for a turbomachine, comprises an aerodynamic profile (61) formed from a body (70) made from a first material, and an add-on part (74) fixed to the body (70) by brazing and made from a second material. The add-on part (74) is housed in a recess (72) formed in a median part of an end part (73) of the body (70), between extreme parts (73A, 73B) of the end part, such that the add-on part (74) forms a median portion of the leading edge (62) of the aerodynamic profile (61). The second material has a coefficient of linear thermal expansion along the direction of the leading edge greater than that of the first material, at a normal operating temperature of the vane (54), which reduces risks of cracks appearing in the aerodynamic profile (61).
