    摘要: A coating for use on a superalloy substrate comprising a diffusion barrier as an intermediate layer overlying the substrate and underlying a protective coating having a high aluminum content. The diffusion barrier layer is characterized by having low solubility for aluminum from either the substrate or the protective coating. Further, the diffusion barrier layer has low interdiffusivity for elements from the substrate and the coating, a minimal impact on the mechanical properties of the article which is coated, a minimal thermal expansion mismatch with both the substrate and the high aluminum content protective coating, and can be applied readily using existing coating application techniques. The diffusion barrier is preferably a single phase alloy or intermetallic compound.

    摘要: Ni-base alloy foils are made directly from Ni-base alloy powders by hot pressing. These Ni-base alloy foils are characterized by having a thickness of 0.017 in. or less, and by the fact that they are fine-grained and substantially free of oxygen, nitrogen and deformation-induced defects. The as-pressed Ni-base foils are generally ductile and adapted for subsequent forming operations, including cold rolling. The reduction in thickness imparted in a single pass to a Ni-base alloy foil through cold-rolling ranged from 4-10% depending on the alloy composition. The total reduction in thickness ranged from about 10-50% based upon a plurality of such passes. For reductions in thickness greater than about 10%, annealing is employed for stress relief.
