Diffusion bonding is believed to require the breaking of the inhibitory layer of a non-metallic atom, such as oxygen, on the bonding plane by atomic diffusion and to require contact between each bonding plane. At a high enough temperature, atomic diffusion of each grain boundary and intraparticle occurs and oxygen in the inhibitory layer is ...

For an undoped FeAl alloy, premature spallation of the alumina film occurs due to the formation of numerous voids at the film/alloy interface and apparent shrinkage in the film. In contrast to this, doping with either Hf or Y significantly improves the interfacial adhesion between the ...
