Abstract
Slurry coating compositions are provided for metal substrates, particularly nickel or cobalt-containing alloys, that enable inward-type diffusion aluminide coatings having a substantially uniform coating thickness to be formed thereon. Substantially uniform coating thicknesses are achieved independent of applied slurry composition thickness or application method. The slurry coating composition of the invention comprises a Cr--Al alloy containing about 50 wt % to about 80 wt % Cr in the alloy, LiF in an amount greater than or equal to 0.3 wt % of the Cr--Al alloy, an organic binder, and a solvent.
