Abstract
A process for applying a chromized layer on a substrate by first applying an overlay coating to a portion of the substrate, and subsequently contacting a different portion of the substrate and the overlay with a gas containing gaseous chromium, wherein the gaseous chromium can be generated from a chromium source and an activator. The process prepares the substrate, often a jet engine airfoil, for service.
