Hot corrosion-resistant coatings and components protected therewith
A coating system (14,34) on a superalloy or silicon-containing substrate (12,32) of an article (10,30) exposed to high temperatures. The coating system (14,34) includes a coating layer (16,18,20,22,24,36,38) that overlies the substrate (12,32) and is susceptible to hot corrosion promoted by molten salt impurities. A corrosion barrier coating (26) overlies the coating layer (16,18,20,22,24,36,38) and contains at least one rare-earth oxide-containing compound that reacts with the molten salt impurities to form a dense, protective byproduct barrier layer (28).
