Abstract
A method for preparing an aluminum alloy-containing coating composition is described. A slurry containing a selected amount of aluminum is combined with at least one additional slurry containing a selected amount of a second metal which forms an alloy with aluminum. The resulting slurry mixture is applied to a metal substrate, and then heated to form a substantially devolatilized coating. The coating then receives a secondary heat treatment. Related compositions and articles are also described, as are processes for repairing a damaged or worn coating, utilizing the slurry.
