Mechanism of adhesion of alumina on M-chromium-aluminum-yttrium (M = iron, nickel, cobalt) alloys

Mechanism of adhesion of alumina on M-chromium-aluminum-yttrium (M = iron, nickel, cobalt) alloys. Luthra, Krishan L.; Briant, Clyde L. (Gen. Electr. Corp. Res. and Dev., Schenectady, NY 12301, USA). Oxid. Met., 26(5-6), 397-416 (English) 1986. CODEN: OXMEAF. ISSN: 0030-770X. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 55 X-ray diffraction was used to measure strains/stresses generated in oxide films formed under isothermal conditions at 1150-1225° and cooled to room temp. High compressive strains, ~1%, were measured in alumina films formed on FeCrAlY [58719-23-6]. 63414-34-6 and 7439-89-6 are also in the experiment. Little or no strain was measured in oxide films on NiCrAlY [58439-75-1] and NiCoCrAlY [63414-34-6] samples, even when there was no scale spallation. AES expts. were conducted to evaluate the role of segregation on scale adhesion. The adhesion mechanism depends on the alloy compn. On Fe alloys, the scale spallation is prevented by mechanisms that involve strong bonding at the interface. The scale spallation on Ni alloys is prevented by a mechanism that relieves stresses. Y segregation helps in this process. .
