Beschreibung
Zusammenfassung:	A heat exchanger (400; 900) for a gas turbine engine (110) is provided and comprises a baffle (436, 16) comprising a cobalt alloy configured to form an oxidized layer (30) over an outer surface of the baffle (436, 16) in response to an increase in temperature, the oxidized layer providing a lubricating surface. The heat exchanger further comprises a tube (22) inserted at least partially through the baffle (436, 16), an inlet (12) coupled to a first end of the tube (22), and an outlet (14) coupled to a second end of the tube (22).
