Abstract
In the method of forming diffusion coatings for improved corrosion, erosion or wear properties in high performance alloy structures, the coatings being characterized by the intimate presence of an interdispersed phase material in desired amount to enhance one or more of these properties, which includes interdiffusing under non-oxidizing conditions a portion of the structure surface and an alloying element disposed therewith, such as aluminum, in a diffusion pack of predetermined composition desirable for the interdiffusion, the improvement comprising maintaining the desired amount of interdispersed phase material relatively richly concentrated within a selected pack zone corresponding to the locus of interdiffusion for intimate diffusion coating interdispersal from the pack zone in interdiffusion responsive relation and freely of varying the predetermined composition of the pack.
