Abstract: Dry lubricated members particularly adapted for use as cold side rubbing seals in the regenerator section of gas turbine engines, the members comprising a substrate with an initial working surface of an iron oxide matrix containing an interspersed mixture of graphite and a trapping material in the form of an inorganic compound such as salt or oxide. Subsequent to a breakin period the work surface and any mating surface therewith both acquire a substantially continuous film of high oriented iron hematite - Fe2O3.
