Zusammenfassung:	A method of coating a component including aluminizing (202) an array of internal passageways (110) within the component; and chromizing (206) a portion of the array of internal passageways (110) within the component. A component, including an airfoil (92) having an array of aluminized internal passageways (110), the array of aluminized internal passageways (110) chromized (206) up to a demarcation (140).
