Abstract: A method for repairing a tip portion of a turbine component having a structural defect is provided. The method includes removing a damaged section in turbine component with a structural defect in a tip portion of the turbine component. A pre-sintered preform is provided including a first portion having a first composition and a second portion having a second composition. The pre-sintered preform is configured to mate with an upper surface of a remaining portion of the turbine component. The method also includes applying the pre-sintered preform to the upper surface, wherein the PSP comprises a superalloy material and a braze material. The PSP and the remaining portion of the turbine component are subjected to a brazing process to melt the braze material and fill in the structural defect.

Abstract: A vehicular leaf spring plate tip liner insert is provided, having a variety of configurations (50, 100, 150, 200, 250), of which one preferred embodiment is referenced by numeral (50). Insert (50) has a pad portion (3) adapted to provide a pad between adjacent leaf spring tips and at least one shank portion (4) extending from pad portion (3). Shank portion (4) is axially divided into two pairs of opposed protuberances (14, 14' and 16, 16'), with each pair having surfaces in registration with each other that are at different axial distances from pad portion (3) and engageable with the side of leaf spring opening opposite to the side into which shank portion (4) is inserted and are able to secure insert (50) to a leaf spring plate having a range of thicknesses upon expanding away from each other upon passing through the leaf spring tip opening.
