Abstract: An article comprises a metal alloy substrate and a plated wear interface layer disposed over a surface of the metal alloy substrate. The wear interface layer has a chemical composition including between about 0.005 wt % and about 0.050 wt % of antimony (Sb), and the balance silver (Ag) and incidental impurities.

Abstract: A joining method includes performing a first heat treatment step on a first superalloy workpiece and a second superalloy workpiece wherein at least one of the first and second superalloy workpieces include a gamma matrix phase and a gamma-prime precipitate phase. The first and second superalloy workpieces are joined using a solid state joining process, subjected to a post-weld stress relief operation and a final aging heat treatment.

Abstract: A seal assembly for a gas turbine engine may include a seal body coupled to an engine static structure of the gas turbine engine and a seal seat insert coupled to a radially extending portion of a shaft of the gas turbine engine. The seal body may be generally configured to be biased into contact with the seal seat insert to provide a sealing pressure between the seal body and the seal seat insert. In various embodiments, the seal seat insert is made from a ceramic material or a ceramic matrix composite.
